When formic acid or oxalic acid is treated with conc. `H_(2)SO_(4)` , the gas evolved is

A

`H_(2)S`

B

CO

C

`SO_(2)`

D

`CO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`{:(CO OH),("|"),(CO OH):} overset(Conc. H_(2)SO_(4))toCO+CO_(2)+H_(2)O`
`HCO OH overset(Conc. H_(2)SO_(4))toCO +H_(2)`
Conc. `H_(2)SO_(4)` acts as a dehydrating agent eliminates water.
