Given below are two statements : Statement I : under Clemmensen reduction conditions will give Statement II : under Wolff-Kishner reduction condition will give In the light of the above statements, choose the correct answer from the options given below :

Options

  1. AStatement I is false but Statement II is true
  2. BBoth Statement I and Statement II are false
  3. CStatement I is true but Statement II is false
  4. DBoth Statement I and Statement II are true

Correct answer

C. Statement I is true but Statement II is false

Step-by-step solution

The Clemmensen reduction is a reaction that is used to reduce aldehydes or ketones to alkanes using hydrochloric acid and zinc amalgam. In this reaction amide can undergo hydrolysis to convert into carboxylic acid. The Wolff–Kishner reduction is a reaction used in organic chemistry to convert carbonyl functionalities into methylene groups in the presence of hydrazine in basic medium. Due to the alkaline medium, alkyl halides undergo beta elimination to convert into alkene as shown below.
