Question

Electrolysis of concentrated aqueous solution of a compound gave ${\text{C}}_{\text{2}}{\text{H}}_{\text{6}}$ on anode. The compound is:

• A. ${\text{CH}}_{\text{3}}\text{COOK}$
• B. ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}\text{COOK}$
• C. ${\text{CH}}_{\text{3}}{\text{COOC}}_{\text{2}}{\text{H}}_5$
• D. ${\text{CH}}_{\text{3}}{\text{OCH}}_{\text{3}}$

Answer 1

Answer: (A)

${\text{CH}}_{\text{3}}\text{COOK}$

Ethane is formed at anode through electrolysis of $C{H}_{3}COO$ $K$

At anode:

$C{H}_{3}CO{O}^{⊝}⟶C{H}_3^o+C{O}_2$

$2C{H}_3^o⟶C_2{H}_6$
