Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R.
Assertion A:
can be easily reduced using Zn $$-$$ Hg/HCl to
.
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:
The reactant provided is a keto-alcohol (contains both a carbonyl group, $$\text{C=O}$$, and a hydroxyl group, $$\text{--OH}$$). When treated with Clemmensen reducing agent (amalgamated zinc and concentrated hydrochloric acid, $$\text{Zn--Hg/HCl}$$), two distinct chemical transformations happen simultaneously:
Since the final product doesn't accurately shows the carbonyl converted to a alkane linkage and the hydroxyl replaced by chlorine, Assertion A is FALSE.
Reason (R) states that $$\text{Zn--Hg/HCl}$$ is standardly employed to reduce a carbonyl group down to a active methylene ($$\text{--CH}_2\text{--}$$) group. This is the fundamental definition of a Clemmensen reduction, making Reason R perfectly TRUE as an independent chemical statement.
