Moderate

The most probable products when CI2 is supplied in very high excess to react with CH4:

Correct answer: D. CH2Cl2 + 2HCl

  • A. CH3Cl + HCl
  • B. CHCl3 + 3HCl
  • C. CCl4 + 4HCl
  • D. CH2Cl2 + 2HCl

Explanation

The free-radical chlorination of methane is a chain reaction. When chlorine is used in large excess, the reaction will continue until the methane is fully substituted, leading to carbon tetrachloride (CCI4) and hydrogen chloride (HCI) as the final major products.
