Carbon monoxide on heating with NaOH at ...

Carbon monoxide on heating with `NaOH` at `200^(@) C` under `6-10 atm` pressure yields.

A

sodium formate

B

sodium acetate

C

sodium oxalate

D

sodium carbonate

Text Solution

Verified by Experts

The correct Answer is:
A
Although `CO` is not a true acid anhydride since it does not react with to produce an acid, it reacts under pressure with fused sodium hydroxide to give sodium formate (methanoate):
`NaOH(l) + CO(g) rarr HCOONa(s)`
Formic acid (methanoic acid) is produced from the sodium salt by the addition of dilute hydrochloric acid.
