Assertion: Aldehyde and keton ungergo nucleophilic addition reaction with carbon nucleophile and undergo nucleophilic addition-climination reaction with nitrogen Nucleophile.
Reason : Addition of nuclephile on aldehyde and keton form retrahedral intermediate , in case of tertahedral intermediate of nitrogen nucleophile nonbonding molecule to eliminate while in case of carbon and hydrogen nucleophile nonbonding electron are not present.
