Question

The reaction of chloroform with Ag powder gives ______. 

Options

• \[\ce{CH4}\]

• \[\ce{CH2 = CH2}\]

• \[\ce{CH ≡ CH}\]

• \[\ce{HCOOAg}\]

Answer 1

The reaction of chloroform with Ag powder gives \[\ce{CH ≡ CH}\].

Explanation:

When heated with silver powder, chloroform (or iodoform) goes through a dehalogenation process and becomes acetylene.

\[\ce{CHCl3 + 6Ag + CHCl3 ->[Δ] CH ≡ CH + 6AgCl}\]

Chloroform        Chloroform      Acetylene
