Given below are two statements, one is labelled as AssertionAand the other is labelled as ReasonR.
AssertionA:can be subjected to Wolff-Kishner reduction to give
ReasonR: Wolff-Kishner reduction is used to convertinto
In the light of the above statements, choose the correct answer from the options given below:

Options:

Answer:
B
Solution:

The reagent hydrazine in alkaline medium is used in the Wolff-Kishner reduction reaction. In this reaction aldehydes and ketone converts to respective alkanes.

This reaction is not good for base sensitive groups in the carbonyl compounds.  The following chloro carbonyl compound give alkene as elimination reaction expected in basic medium.
