Q. Which compound does not give precipitate with ammoniacal silver nitrate solution?
A) $C_{2}H_{5} - C \equiv CH$
B) $CH_{3} - C \equiv C - CH_{3}$
C) $CH_{3}$
|
$CH_{3} - CH - C \equiv CH$
D) $Ph - CH_{2} - C \equiv CH$
Explanation
(b)
Only terminal alkynes give precipitate with ammoniacal silver nitrate solution.
Among the given, $CH_{3} - C \equiv CH - CH_{3}$ is not a terminal alkyne. Thus, it does not give precipitate with ammoniacal $AgNO_{3}$.
