Question 8

Why do aldehydes undergo nucleophilic addition reactions while esters undergo nucleophilic acyl substitution reactions?

Accepted Answer

A) The carbonyl carbon of an ester is more electrophilic than that of an aldehyde. 
B) 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 an aldehyde,neither H- nor R- can be eliminated since they are strongly basic.
