Acetic acid is reacted with metallic sodium to form hydrogen and $X$. When $X$ is heated with sodalime, $Y$ and sodium carbonate are formed. $Y$ is

• A

  $\mathrm{C}_2 \mathrm{H}_6$
• Correct answer
  B

  $\mathrm{CH}_4$
• C

  $\mathrm{CH}_3 \mathrm{COONa}$
• D

  $\mathrm{CH}_3 \mathrm{CONH}_2$

Hence, the correct answer is option: 'B'.
