Why do aldehydes undergo nucleophilic addition reactions while esters
undergo nucleophilic acyl substitution reactions?
(a) The carbonyl carbon of an ester is more electrophilic than that of an aldehyde.
(b) Aldehydes are more sterically hindered than esters.
(c) Once the nucleophile adds to an aldehyde, the tetrahedral intermediate is too
sterically hindered to eliminate one of the attached groups.
(d) Once the nucleophile adds to an aldehyde, neither H− nor R− can be
eliminated since they are strongly basic
