Reactions

SN1 reactions, E1 reactions, the addition of hydrogen halides across C=C double bonds, the acid dehydration of alcohols, and electrophilic aromatic substitutions entail the formation of an intermediate structure. What is the name of this structure? answerCarbocation

Grignard reactions and aldol condensations involve what type of organic ion? answerCarbanion

What basic type of reaction are esterification, saponification, hydrolysis, ammonolysis, transesterification, various polymerizations, and many biochemical reactions? answerSN2 (second order nucleophilic substitution) reactions

Why do carbonyl compounds tend to undergo nucleophilic addition while carboxylic acids tend to undergo nucleophilic substitution? answerThe -OH group in carboxylic acids is a relatively good leaving group, facilitating substitution. Carbonyl compounds do not have -OH groups or othergood leaving groups, and so substitutions are not favored.They can, however, have addition across their C=O double bond.
