Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R.
Assertion Acan be subjected to Wolff-Kishner reduction to give 
Reason R: Wolff-Kishner reduction is used to convert  into 
In the light of the above statements, choose the correct answer from the options given below:
  1. A is true but R is false
  2. A is false but R is true
  3. Both A and R are true and R is the correct explanation of A
  4. Both A and R are true and R is NOT the correct explanation of A

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.
