MCQ
Which of the following has acidic hydrogen
- ✓Ethyne
- BEthene
- CEthane
- DBenzene
✓
Answer
Correct option: A.
Ethyne
a
(a) $2CH \equiv CH + 2Na \to 2CH \equiv {C^ - }N{a^ + } + {H_2}$
(a) $2CH \equiv CH + 2Na \to 2CH \equiv {C^ - }N{a^ + } + {H_2}$
Reaction with sodium metal shows that hydrogen is acidic.
