Question

Slow oxidation of chloroform in air leads to the formation of:

• A. formyl chloride
• B. formic acid
• C. $CO{Cl}_2$
• D. trichloro acetic acid

Answer 1

The correct option is C $CO{Cl}_2$

Slow oxidation of chloroform in air leads to the formation of phosgene or carbonyl chloride $COC{l}_2$
$CHC{l}_3+\frac{1}{2}{O}_2\stackrel{light}{\to }COC{l}_2+HCl$
Note: Phosgene is highly poisionous substance used in warfare.
