Organic Chemistry Name Formula Isomers Methane CH 1 Ethane C H
Organic Chemistry Organic chemistry is the chemistry of carbon. The simplest carbon molecules are compounds of just carbon and hydrogen, hydrocarbons. We name the compounds based on the length of the longest carbon chain. We then add prefixes and suffixes to describe the types of bonds and any add-ons the molecule has. When the molecule has just single bonds we use the -ane suffix. Name Formula Isomers Methane CH4 1 Ethane C2H6 1 Propane C3H8 1 Butane C4H10 2 Pentane C5H12 3 Hexane C6H14 5 Heptane C7H16 9 Octane C8H18 18 Nonane C9H20 35 Decane C10H22 75 Isomers are compounds that have the same formula but different bonding. isobutane n-butane 1 Naming Alkanes Hydrocarbons are always named based on the longest carbon chain. When an alkane is a substituent group they are named using the -yl ending instead of the -ane ending. So, -CH3 would be a methyl group. The substituent groups are named by numbering the carbons on the longest chain so that the first branching gets the lowest number possible. The substituents are listed alphabetically with out regard to the number prefixes that might be used. 3-methylhexane 1 2 3 4 5 6 6 5 4 3 2 1 Alkenes and Alkynes When a hydrocarbon has a double bond we replace the -ane ending with -ene. When the hydrocarbon has more than three carbon the position of the double bond must be specified with a number. 1-butene 2-butene Hydrocarbons with triple bonds are named basically the same, we replace the -ane ending with -yne. -
Stoichiometric and Catalytic Reactions Involving Si-H Bond Activations by Rh and Ir Complexes Containing a Pyridylindolide Ligand Dmitry Karshtedt,†,‡ Alexis T
Organometallics 2006, 25, 4471-4482 4471 Stoichiometric and Catalytic Reactions Involving Si-H Bond Activations by Rh and Ir Complexes Containing a Pyridylindolide Ligand Dmitry Karshtedt,†,‡ Alexis T. Bell,*,§,‡ and T. Don Tilley*,†,‡ Departments of Chemistry and Chemical Engineering, UniVersity of California, Berkeley, Berkeley, California 94720, and Chemical Sciences DiVision, Lawrence Berkeley National Laboratory, 1 Cyclotron Road, Berkeley, California 94720 ReceiVed June 5, 2006 New rhodium and iridium complexes containing the bidentate, monoanionic 2-(2′-pyridyl)indolide (PyInd) ligand were prepared. The bis(ethylene) complex (PyInd)Rh(C2H4)2 (3) reacted with triethylsilane at 60 °C to produce the 16-electron Rh(V) bis(silyl)dihydride complex (PyInd)RhH2(SiEt3)2 (4). Both 3 and 4 catalyzed the chloride transfer reaction of chlorobenzene and Et3SiH to give Et3SiCl and benzene i in the absence of base. In the presence of LiN Pr2, catalytic C-Si coupling was observed, to produce Et3SiPh. Analogous Ir complexes of the type (PyInd)IrH2(SiR3)2, where R3 ) Et3 (6a), Me2Ph (6b), Ph2Me (6c), or Ph3 (6d), were not catalytically active in this chloride transfer chemistry. The molecular structure of 6c, determined by X-ray crystallography, may be described as having a highly unusual bicapped tetrahedral geometry. DFT calculations indicate that this distortion is associated with the d4 electron count and the presence of highly trans-influencing silyl ligands. The reaction of 6a with PMe3 (5 equiv) produced (PyInd)IrH(SiEt3)(PMe3)2 (7), while the reaction with PPh3 (1 equiv) generated a mixture of isomers that was converted to (PyInd)IrH(SiEt3)(PPh3)(8) upon heating in benzene at 80 °C. -
Addition of Hydrogen Bromide to Unsymmetrical Olefins
AN ABSTRACT OF TH TESIS OF Charles runior Rogers for the Ph.D. in Chemistry (Name) (Degree) (Lajor1 Date thesis is presented August 22, 1952 - Title ADDITION OF HYDROGEN BROMIDE Abstract approved Redacted for privacy (Ljr Pro'essor) (j In this investigation the addition o1 hydrogen bromide to 3-methylcyclohexene has been studied in order to see if the theory of hyperconjugation could be extended to include olefins of' this type. Since the olefin has an equal number of hydrogens on both carbons carrying the double bond, a mixture o± bromides was expected in the addition product. The bromides expected were cis-2- or trans-2-bromomethyl- cyclobexane or a mixture of the isomers and ois-3- or trans-3-broraomethylcyclohexane or a mixture or those isomers. An infrared method ol' analyzing the addition product was used. To use this method it was necessary to make up 1own mixtures of the compounds expected in the addition product. In order to prepare some of the isomeric bromides, trams-2- and trans-3-rnethylcyclohexanol were prepared. Then, because no good. methods could be found in the literature for the conversion of isomeric alcohols to isonieric bromides, the alcohols were not used. Instead, the Imown mixtures for the infrared work were prepared from 2-bromo- and 3-bromo- methylcyclohexanes, both containing unknown amounts of the cis-trans isomers. The 3-methylcyclohexene used in the hydrogen bromide addition was prepared from. 3-bromom.ethylcyclohexene and methylnìagnesium iodide. The addition of hydrogen bromide was conducted at 0°C and at room temperature using glacial acetic acid as a solvent. -
Methane Or Pentane Calibration
July 10, 2003 Applications Note: Use of "pentane equivalent" calibration gas mixtures Introduction The gas that is used to verify accuracy is every bit as important as the detector itself when it comes to worker safety. Choosing (and using) the right mixture is critical to the success of your atmospheric monitoring program. BW understands the importance of calibration, and we are always on the lookout for ways to improve the process. To that end, BW is pleased to announce the introduction of a new series of "pentane equivalent" calibration gas mixtures. These mixtures are designed to provide an even more dependable (and easy) means for the verification of accuracy of instruments that include a sensor for the detection of combustible gas. What are "pentane equivalent" mixtures and why are they better? Using BW’s new "equivalent" mixtures is exactly like using our older mixtures. In the case of the GasAlertMicro and GasAlertMax, all you have to do is press the "cal" button, attach the adaptor, and flow gas to the sensors. All the adjustments are made automatically. The difference comes from what's in the cylinder of gas. In the past, BW has usually recommended using mixtures that include 50% LEL methane as the combustible gas used for general purpose calibration. BW's new equivalent mixtures are still based on methane, but in concentrations that are designed to produce a level of sensitivity "equivalent" to that provided by a mixture that contains a 50% LEL concentration of pentane. The reasoning behind the development of these new formulations has to do with how combustible sensors detect gas, and what happens to sensitivity in the event that a combustible sensor ever becomes "poisoned". -

FACT SHEET Pentane, All Isomers
FACT SHEET Pentane, All Isomers CAS Numbers: n-Pentane: 109-66-0; Isopentane: 78-78-4; Neopentane: 463-82-1 This fact sheet provides a summary of the Development Support Document (DSD) created by the TCEQ Toxicology Division (TD) for the development of Regulatory Guidelines (ESLs, AMCVs and ReVs) for ambient exposure to this chemical. For more detailed information, please see the DSD or contact the TD by phone (1-877-992-8370) or e-mail ([email protected]). What is pentane? Pentane is a colorless, volatile and flammable liquid with a sweet or gasoline-like odor. Pentane consists of three isomers: n-pentane, isopentane, and neopentane. n-Pentane is an ingredient of crude oil and a component of the condensate from natural gas production. It is primarily obtained from the processing of crude oil. n-Pentane is used as a component of gasoline blends, as an aerosol propellant, as a blowing agent for foams, and as a solvent. Isopentane is also used as a blowing agent, and neopentane is used in the manufacture of butyl rubber. How is pentane released into ambient air? Pentane can be released into the air from industrial uses or production plants and from natural gas production. It is also released to the environment during its use in adhesives and glues. Pentane released to the environment is expected to volatilize to the atmosphere, where it will undergo photochemical oxidation reactions. How can pentane affect my health? Permitted levels of pentane should not cause adverse health and welfare effects. Pentane produces minor lung irritation. Based on animal studies, inhalation of extremely high concentrations of pentane (i.e., concentrations above the lower explosive limit of 14,000 ppm) may affect the nervous system or cause irritation of the nose and throat. -

Ziegler* School of Chemical Engineering Georgia Institute of Technology SUMMARY This paper presents a brief review of the literature pertaining to the vapor pressure of eleven hydrocarbons at low temperatures. These hydrocarbons are methane, ethane, propane, n-butane, iso- butane (2-methyl propane), n-pentane, ethylene, propylene, 1-butene, acetylene and cyclopropane. All of these except cyclopropane are encountered in the purification of hydrogen from refinery sources. Vapor pressure data are given for most of these hydrocarbons over the pressure range 0. 001 to 1500 mm Hg. These data have been used to estimate the triple-point pressures of the hydrocarbons where these pressures were not found in the literature. -
