MCQ
One of the following molecular formula can represent two organic compounds having different functional groups. This molecular formula is :
  • A
    $\mathrm{C}_5 \mathrm{H}_{12} \mathrm{O}$
  • ✓
    $\mathrm{C}_5 \mathrm{H}_{10} \mathrm{O}$
  • C
    $\mathrm{C}_5 \mathrm{H}_{10} \mathrm{O}_2$
  • D
    $\mathrm{C}_5 \mathrm{H}_{12}$
✓

Answer

Correct option: B.
$\mathrm{C}_5 \mathrm{H}_{10} \mathrm{O}$
$\mathrm{C}_5 \mathrm{H}_{10} \mathrm{O}$ represents two organic compounds ketones $\left(\mathrm{C}_2 \mathrm{H}_5-\mathrm{CO}-\mathrm{C}_2 \mathrm{H}_5\right)$ and aldehydes $\left(\mathrm{C}_2 \mathrm{H}_5-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{CHO}\right)$ which have different functional groups.
