Identify A and B.


Open in App
Solution

Hydrolysis of calcium carbide CaC2 leads to the formation of acetylene.

CaC2(aq)HydrolysisC2H2(aq)

When acetylene is reacted with the mixture of HgSO4 + Dil H2SO4, It leads to the formation of acetaldehyde (CH3CHO).

Therefore,

C2H2(aq)HgSO4+Dil.H2SO4CH3CHO(aq)

The whole reaction can be written in this way

CaC2(aq)HydrolysisC2H2(aq)HgSO+Dil.HSO4CH3CHO(aq)

Therefore, Compound A is C2H2 (acetylene) and Compound B is acetaldehyde i.e ., CH3CHO.
