Question

The concentrated aqueous solution of potassium salts of acetic acid and propanoic acid are electrolysed. Which of the following hydrocarbon(s) is/are produced? (A) CH3CH3 only (B) CH3CH2CH3 only (C) CH3CH3 and CH3CH2CH2CH3 (D) CH3CH2CH2CH3 and CH3CH2CH3

When concentrated aqueous solution of potassium salts of acetic acid and propanoic acid are electrolysed.

C H_{3} C H_{3}

and

C H_{3} C H_{2} C H_{2} C H_{3}

are produced as follows

C H_{3} COO K (a q) \to C H_{3} CO O^{-} (a q) + K^{+} (a q)

C H_{3} C H_{2} COO K (a q) \to C H_{3} C H_{2} CO O^{-} (a q) + K^{+} (a q)

Anode: A.

2 C H_{3} CO O^{-} (a q) \to C H_{3} - C H_{3} + 2 C O_{2} + 2 e^{-}

B.

2 C H_{3} C H_{2} CO O^{-} (a q) \to C H_{3} C H_{2} C H_{2} C H_{3} + 2 C O_{2} + 2 e^{-}

Cathode:

2 H O H + 2 e^{-} \to H_{2} (g) + 2 O H^{-}
