Answer 2

Answer:

The correct meaning of A, B, C, D is A = Propan-2-ol, B = Propene, C = Propyne, D = Acetone

Explanation:

The reactions that are given in the question can be summarised as follows:

From the above reaction it seems that C is an Alkyne and D is an Aldehyde or ketone.

Since D can be obtained from acetic acid through its calcium salt it must be either acetaldehyde or acetone.

Hence proceeding backwards A must be isopropyl alcohol.
