The compounds formed at anode in the electrolysis of an aqueous solution of potassium acetate, are

A)  \[{{C}_{2}}{{H}_{6}}\]and \[C{{O}_{2}}\]              

B)  \[{{C}_{2}}{{H}_{4}}\]and \[C{{O}_{2}}\]

C)         \[C{{H}_{4}}\]and\[{{H}_{2}}\] 

D)         \[C{{H}_{4}}\]and \[C{{O}_{2}}\]

Correct Answer: A

Solution :

This is an example of Kolbes electrolysis. \[2C{{H}_{3}}COOK\xrightarrow{electrolysis}2C{{H}_{3}}CO{{O}^{-}}+2{{K}^{+}}\] At cathode: \[2{{K}^{+}}+2{{e}^{-}}\xrightarrow{{}}2K\] At anode:
