MCQ
Given below are two statements: One is labelled as Assertion $A$ and the other is labelled as Reason $R$.

Assertion $A$ : $Image-I$ can be easily reduced using $Zn - Hg / HCl$ to $Image-II$

Reason $R : Zn - Hg / HCl$ is used to reduce carbonyl group to $- CH _2-$ group.

In the light of the above statements, choose the correct answer from the options given below:

  • $A$ is false but $R$ is true
  • B
    $A$ is true but $R$ is false
  • C
    Both $A$ and $R$ are true but $R$ is not the correct explanation of $A$
  • D
    Both $A$ and $R$ are true and $R$ is the correct explanation of $A$

Answer

Correct option: A.
$A$ is false but $R$ is true
a
The acid sensitive alcohol group reacts with $HCl$, hence Clemmenson reduction is not suitable for above conversion.
