In mechanism for electrophilic aromatic substitution reactions of aromatic compounds, what is the driving force for deprotonation in the last step? To neutralize any base that is present To allow for addition across the ring's double bonds. To make room for the electrophile To restore aromaticity to the ring system. To make the ring into a better nucleophile
Electrophilic Aromatic Substitution The most common reactions of aromatic compounds involve the substitution of other atoms or groups for a ring hydrogen: Fech + CI chlormation + Br FeBry bromination HNO3 H,SO nitration (HONO) H,SO sulfona (HOSO,H) AICH + RC- alkylation H,80 + CH=CH alkylation + RCCI - acvlation CH2CH2CH2CH3 Oxidation KMnO4 Ho CH3 Reduction Hy.

9) 9) Why do aldehydes undergo nucleophilic addition reactions, whereas esters undergo nucleophilic acyl substitution reactions? A) The carbonyl carbon of an ester is more electrophilic than that of an aldehyde. B) Once the nucleophile adds to an aldehyde, neither H- nor R-can be eliminated because they are strongly basic. C) Aldehydes are more sterically hindered than esters. D) The ester carbonyl carbon is sp3 hybridized while the aldehyde carbonyl carbon is sp2 hybridized. E) Once the nucleophile adds to...
