Carbon monoxide on heating with `NaOH` at `200^(@) C` under `6-10 atm` pressure yields.A. sodium formateB. sodium acetateC. sodium oxalateD. sodium carbonate

Answer» Correct Answer - 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.
