The compound most suitable for the preparation of cyanohydrin is

• A

  $\mathrm{C}_2 \mathrm{H}_5 \mathrm{COOH}$
• B

  $\mathrm{C}_6 \mathrm{H}_5 \mathrm{NH}_2$
• Correct answer
  C

  $\mathrm{C}_2 \mathrm{H}_5 \mathrm{COC}_2 \mathrm{H}_5$
• D

  $\mathrm{C}_2 \mathrm{H}_5-\mathrm{C}_2 \mathrm{H}_5$.

Solution

Cyanohydrin can be prepared easily by the reaction of $\mathrm{HCN}$ with carbonyl compounds (i.e. Ketones)

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