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...
