MHT CET Chemistry Question (2026) — Solution

Question

Which of the following compounds is formed when chloroform is exposed to air and light?

Options

  1. A. Phosgene.
  2. B. Phosphine.
  3. C. Carbon dioxide
  4. D. Carbon tetrachloride

Answer

A. Phosgene.

Step-by-step solution

Chloroform (CHCl_3) undergoes slow oxidation in the presence of air and light to form a highly poisonous gas called phosgene (COCl_2). The chemical equation for this reaction is: 2CHCl_3 + O_2 h 2COCl_2 + 2HCl Thus, phosgene is the compound formed. Answer: Phosgene.
