In the following sequence of reactions, the end product is
`CaC_(2) overset(H_(2)O)rarr A overset(Hg^(2+)//H_(2)SO_(4))rarr B overset([O])rarr C overset(Ca(OH)_(2))rarr D overset("heat")rarr E`

Options

A. acetaldehyde
B. formaldehyde
C. acetic acid
D. methane

Answer

D

Explanation

`CaC_(2) overset(H_(2)O)rarr underset((A))(HC -= CH) overset(Hg^(2+),H^(+))rarr underset((B))(CH_(3)CHO) overset(O)rarr underset((C))(CH_(3)COOH) overset(Ca(OH)_(2))rarr underset((D))((CH_(2)COO)_(2)Ca) underset(-CaCO_(3))overset("Heat")rarr underset((E))(CH_(3)COCH_(3))`
