C) Methane reacts with chlorine in the presence of sunlight is example of substitution reaction.

  • One atom from one molecule is replaced with an atom from another one in a substitution process.
  • CH4 + Cl2 → CH3Cl + HCl
  • Chlorine substitutes one hydrogen of methane. Therefore is a substitution reaction.
  • It is a substitution reaction in which a chlorine atom replaces one of an alkane's hydrogen atom to produce an alkyl chloride. This reaction can only occur in the presence of light and produces both an alkyl halide and hydrogen chloride.
  • Properties of chloromethane:
  1. It has a light odour and is a clear, colourless gas.
  2. It is highly flammable and poisonous.
  3. It weighs more than air.
  4. It is water soluble.
  • If there is too much chlorine present, the process continues, and the four hydrogen atoms are all replaced by four chlorine atoms, forming carbon tetrachloride (CCl4).

Therefore, Methane reacts with chlorine in the presence of sunlight is example of substitution reaction.
