A red precipitate of copper (I) carbide is formed when ammonium solution of copper (I) chloride is introduced into
- CH3CH2CH2CH3
- CH2 = CH - CH2CH3
-
HC≡CH
- CH3 - C = C - CH3
The correct answer is: C
Explanation
When ethyne is passed through an ammoniacal solution of copper(I) chloride, a red-brown precipitate of copper(I) acetylide is produced. Terminal alkynes also react to form a red-brown precipitate
