MCQ
Above conversion can be achieved by
  • A
    Wolf-Kishner reduction.
  • Clemmensen reduction
  • C
    $LiAlH_4$
  • D
    $NaBH_4$

Answer

Correct option: B.
Clemmensen reduction
b
$(b)$ Quaternary ammonium ion shown below would undergo a Hoffmann  elimination reaction under the basic conditions required for the Wolff-Kishner  reduction, but it would be inert to the conditions of the Clemmensen reduction.
