Single Choice

The gases (B), (C) and (D), respectively, are:

A$$HC \equiv CH$$, $$CO_2$$ and $$H_2$$
B$$HC \equiv CH$$, $$H_2$$ and $$CO_2$$
C$$CH_3-C\equiv C-CH_3$$, $$CO_2$$ and $$H_2$$
Correct Answer
D$$CH_3-C\equiv C-H$$, $$H_2$$ and $$CO_2$$

Solution

The gases B, C, D are propyne, $$CO_2$$ and $$H_2$$ respectively.
At cathode, propyne and carbon dioxide are obtained from the electrolysis of potassium 2-methylsuccinate and at anode hydrogen is obtained from the reduction of water.
