Which of the following compound is most reactive towards nucleophilic addition reaction?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Formaldehyde
The most reactive compound towards nucleophilic addition reaction is:
Formaldehyde
- Reactivity order: Formaldehyde > Other aldehydes > Ketones
- Formaldehyde has no alkyl groups, so:
- Least steric hindrance
- No +I effect to reduce the electrophilicity of the carbonyl carbon
Hence, it is attacked most easily by nucleophiles.
