`CaC_(2)+H_(2)Orarr A overset(H_(2)SO_(4) // HgSO_(4)) rarr B`. Identify `A` and `B` in the given reaction

A

`C_(2)H_(2) and CH_(3) CHO`

B

`CH_(4) and HCOOH`

C

`C_(2)H_(4) and CH_(3) COOH`

D

`C_(2)H_(2) and CH_(3) COOH`

Text Solution

Verified by Experts

The correct Answer is:
A
Wohler reaction :
`CaC_2 + 2H_2O rarr C_2H_2 + Ca(OH)_2`
`underset("Acetylene")(C_2H_2) overset(dil. H_2SO_4//HgSO_4)underset(60^@C)rarr underset("Unstable")([CH_2=CHOH])rarr underset("Acetaldehyde")(CH_3CHO)`
