Formation of cyanohydrin form an aldehyde is an example of:
Correct answer: C. Nucleophilic addition
- A. Nucleophilic substitution
- B. Electrophilic addition
- C. Nucleophilic addition
- D. Electrophilic substitution
Explanation
The formation of cyanohydrin is achieved by addition of HCN to carbonyl compounds. As this addition is initiated by the attack of -CN- to carbonyl carbon of carbonyl compound. Therefore, it is a nucleophilic addition reaction.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
