When chlorine water is exposed to sunlight, $\mathrm{O}_{2}$ is liberated. Hence,

  • A
    hydrogen has little affinity to $\mathrm{O}_{2}$
  • B
    hydrogen has more affinity to $\mathrm{O}_{2}$
  • Correct answer
    C
    hydrogen has more affinity to chlorine
  • D
    it is a reducing agent

Solution

$\mathrm{Cl}_{2}+\mathrm{H}_{2} \mathrm{O} \rightarrow 2 \mathrm{HCl}+\frac{1}{2} \mathrm{O}_{2}$ Hydrogen has more affinity for chlorine.

Hence, the correct answer is option: 'C'.
