Question

2$C{H}_{3}CO{O}^{-}N{a}^{+}+2H_{2}O\to C{H}_{3}C{H}_3+2C{O}_2+H_2+2NaOH$
The name of the above reaction is:

• A. Sabatier-Senderens reaction
• B. Wurtz reaction
• C. Kolbe's electrolysis
• D. Friedel-Crafts reaction

Answer 1

The correct option is C Kolbe's electrolysis

2$C{H}_{3}COO-Na$+ + 2$H_{2}O$ $\to$ $C{H}_{3}C{H}_3$+ 2$C{O}_2$+ $H_2$+$2NaOH$

This reaction is known as Kolbe's electrolysis.

The reaction which occurs at anode in this process is:
$2C{H}_{3}CO{O}^{\bullet }\to 2C{H}_3^{\bullet }+2C{O}_2$

$2C{H}_3^{\bullet }\to C_2{H}_6$ and $NaOH$ is formed at cathode.
