- C \(\mathrm{H}_2 \quad \mathrm{C}_2 \mathrm{H}_6, \mathrm{CO}_2\)
- D \(\mathrm{C}_2 \mathrm{H}_6, \mathrm{H}_2 \quad \mathrm{CO}_2\)
Answer & Solution
Correct Answer
(C) \(\mathrm{H}_2 \quad \mathrm{C}_2 \mathrm{H}_6, \mathrm{CO}_2\)
Step-by-step Solution
Detailed explanation
When sodium acetate is electrolysed in aqueous medium, it react as follows \[ 2 \mathrm{CH}_3 \mathrm{COONa}+2 \mathrm{H}_2 \mathrm{O} \longrightarrow 2 \mathrm{CO}_2+2 \mathrm{C}_2 \mathrm{H}_6+2 \mathrm{H}_2 \] At anode (Y): \(\mathrm{C}_2 \mathrm{H}_6+\mathrm{CO}_2\) At…
