In Wolf-Kishner reduction, the carbonyl group of aldehydes and ketones is converted into

In Wolff-Kishner reduction, hydrazine is used alone with a base. Here, the carbonyl functional group is Aldehydes and Ketones 13 converted to the methylene group by addition of 푁퐻2 − 푁퐻2 by which we get hydrazone by the attack of the group to the carbonyl group. It is further reduced to an alkane by addition of ethylene glycol and heating. Therefore, the correct answer is option (a) > CH2 group
