(a)
Interpretation:
The mechanism for the given reaction is to be drawn, and the major product is to be predicted.
Concept introduction:
Sodium hydride is a strong base but a poor nucleophile. So it will deprotonate the alpha carbon of the carbonyl compound. This will generate a strong nucleophile as well as a strong base, the enolate ion. This enolate ion attacks the electrophilic carbon in
(b)
Interpretation:
The mechanism for the given reaction is to be drawn, and the major product is to be predicted for the same reaction.
Concept introduction:
Sodium hydride is a strong base but a poor nucleophile. So it will deprotonate the alpha carbon of the carbonyl compound. This will generate a strong nucleophile as well as a strong base, the enolate ion. This enolate ion attacks the electrophilic carbon in alkyl halides to displace the halide ion in an
