MCQ
The carbonyl carbon is:
- AElectrophilic
- BNucleophilic
- CAmphoteric
- DLewis base
✓
Answer
- Electrophilic
Explanation:
The carbon-oxygen double bond is polarised due to higher electronegativity of oxygen relative to carbon. Hence, the carbonyl carbon is an electrophilic (lewis acid) and carbonyl oxygen is, a nucleophilic (lewis base) centre.
