Q.
Choose the correct order of alkyl group attached to aldehyde that prefer the nucleophilic addition at carbonyl carbon?
Q.
Aldehydes and ketones both contain the carbonyl group.
Q.
Assertion :Ketones are less electrophilic than aldehydes. Reason: The positive inductive effect of the second alkyl radical reinforces that of the first one decreasing still further the partial positive charge on the carbonyl carbon atom.This reduces the attraction of the atom for nucleophilic reagents. Hence ketones are less electrophilic.
