1.

CaC_2+H_2O to A overset(H_2SO_4//HgSO_4)toB. Identify A and B in the given reaction

Answer»

`C_2H_2` and `CH_3CHO`
`CH_4` and HCOOH
`C_2H_4` and `CH_3COOH`
`C_2H_2` and `CH_3COOH`

Solution :Wohler reaction :
`CaC_2 + 2H_2O to C_2H_2 + CA(OH)_2`
`underset"Acetylene"(C_2H_2)underset(60^@C)OVERSET(dil. H_2SO_4//HgSO_4)to underset"UNSTABLE"([CH_2=CHOH]) to underset"Acetaldehyde"(CH_3CHO)`
