Which type of reaction takes place when a carbonyl compound is treated with a mixture of NaCN and an acid?
Correct answer: C. Nucleophilic addition reaction
- A. Electrophilic addition reaction
- B. Substitution reaction
- C. Nucleophilic addition reaction
- D. Displacement reaction
Explanation
The given scenario is an example of a nucleophilic addition reaction, as the reactant, CN- is a nucleophile which adds across the carbonyl bond.Option A describes reactions undergone by alkenes, where an electrophile is added across the carbon-carbon double bond.Option B describes a reaction where one group of atoms is replaced by another group of atoms, but this is not the case here.Option D describes a reaction in which one element is replaced by another element in a compound.

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.
