The given questionis incomplete. The complete question is :

The following product is not obtained during electrolysis of an aqueous solution of sodium formate

(A) H

(B)
CO_2

(C) CH

(D) NaOH

Answer: (C) CH

Step-by-step explanation:

The electrolysis of solution of sodium formate is :

$HCOONa\rightarrow HCOO^-+Na^+$

$H_2O\rightarrow H^++OH^-$

The reactions which occur at anode are:

$2HCOO^-\rightarrow 2HCOO^.\rightarrow 2H^.+2CO_2$

$2H^.\rightarrow H_2$

The reaction which occurs at cathode is:

$Na^++e^-\rightarrow Na$

$2Na+2H_2O\rightarrow 2NaOH+H_2$

The overall reaction is:

$2HCOONa(aq)+2H_2O\rightarrow H_2+CO_2+2NaOH$

Thus CH is not obtained during electrolysis of an aqueous solution of sodium formate
