HOW TO DETERMINE IF YOU ARE BEING EXPOSED The New Jersey Right to Know Act requires most employers to label chemicals in the workplace and requires public employers to provide their employees with information and training concerning chemical hazards and controls. The federal OSHA Hazard Communication Standard, 1910.1200, requires private employers to provide similar training and information to their employees. * Exposure to hazardous substances should be routinely evaluated. This may include collecting personal and area air samples. You can obtain copies of sampling results from your employer. You have a legal right to this information under OSHA 1910.1020. * If you think you are experiencing any work-related health problems, see a doctor trained to recognize occupational diseases.

Theory The high electron density of the ring makes it open to attack by electrophiles HOWEVER...

Recall that in many reactions of alkenes, initial addition of an electrophile (e.g. H+ or "Br+") is followed by addition of a nucleophile to the carbocation intermediate. Draw the product of addition below. Why is this pathway unfavorable in this case? H E X Specific EAS reactions — 1. Halogenation — X FeX3 + X2 (+ HX) (catalyst) (X = Cl, Br) (AlX3 also works as a catalyst) mechanism of formation of the "X+" electrophile: (add the lone pairs and charges) Br Br + FeBr3 Br Br FeBr3 Br Br FeBr3 (Fe3+ is e–-deficient, actual: ! a Lewis acid) EAS mechanism: (complete the resonance structures, and add curved arrows) H Br Br Br FeBr3 Br FeBr3 H H H Br Br Br As mentioned in the text, when the ring is strongly activated by substituents halogenation can take place without catalyst present. X2 alone is electrophilic enough. 2. Nitration — NO H2SO4 2 + HNO3 Formation of the electrophile starts with an acid-base reaction between sulfuric acid and nitric "acid". In this context we should probably call it "nitric base" O O O – H O O H 2 HO S O + HO N HO SO3 + H2O N N O O O O EAS mech: (fill in the missing bits) O H O N O – HSO4 N H or H O O 2 nitrobenzene etc (draw the resonance structures!) 3.
