MCQ
A strong base can abstract an $\alpha -$hydrogen from
- ✓ketone
- Balkane
- Calkene
- Damine
✓
Answer
Correct option: A.
ketone
a
since the carbonyl carbon is electron deficient, so most susceptible to attack by nucleophilic reagents or base. A base increases the acidity of hydrogen atom attached to the $\alpha-C$ of the ketones or aldehydes. That-why $\alpha$ -hydrogen is easily abstracted from ketones by a base, e.g. in aldol condensation reaction, $\alpha$ -hydrogen atom of aldehyde or ketone is abstracted by a strong base.
