Q. Which of the following organic compounds exhibit acidic character?
A) $H_{3}C - C \equiv CH\$
B) $H_{3}C - C \equiv C - CH_{3}$
C) $H_{2}C = CH_{2}$
D) $H_{3}C - CH_{3}$
Explanation
(a)
The H-atoms of terminal alkyne ($ie.,$ $H_{3}C - C \equiv CH)$ is weakly acidic.
$CH_{3} \equiv CH + NaNH_{3}\overset{Liq.{NH}_{3}}{\rightarrow}H_{3}C - CH \equiv CNa + NH_{3}$
