If the tetrahedral product is unstable, it can collapse back to a trigonal carbonyl compound by
expelling a
leaving group.
The overall process of nucleophilic addition followed by leaving group elimination is called
nucleophilic acyl substitution, because the nucleophile replaces the leaving group as a
substituent on the carbonyl carbon.
