The concentrated aqueous solution of potassium salts of acetic acid and propanoic acid are electrolysed. Which of the following hydrocarbon(s) is/are produced?

Options:

Answer:
C
Solution:

When concentrated aqueous solution of potassium salts of acetic acid and propanoic acid are electrolysed.CH3CH3andCH3CH2CH2CH3are produced as follows
CH3COOK(aq)→CH3COO-(aq)+K+(aq)
CH3CH2COOK(aq)→CH3CH2COO-(aq)+K+(aq)
Anode: A.2CH3COO-(aq)→CH3-CH3+2CO2+2e-
B.2CH3CH2COO-(aq)→CH3CH2CH2CH3+2CO2+2e-
Cathode:2HOH+2e-→H2(g)+2OH-
