Which of the following reactions of chlorine are correctly stated?

AMethane reacts with $Cl X_{2}$ in light by free radical substitution.
B $Cl X_{2}$ displaces $F X^{-}$ from $NaF$ to give $F X_{2}$ .
CDry slaked lime absorbs $Cl X_{2}$ to give bleaching powder, $CaOCl X_{2}$ .
D $H X_{2} S$ is oxidised by $Cl X_{2}$ to sulphur.

Answer: A, C, D

Ca (OH) X_{2} + Cl X_{2} CaOCl X_{2} + H X_{2} O

;

H X_{2} S + Cl X_{2} 2 HCl + S

;

CH X_{4} + Cl X_{2} CH X_{3} Cl + HCl

under light. Fluorine is a stronger oxidant than chlorine (E of

F X_{2} / F X^{-}

is larger), so

Cl X_{2}

cannot displace fluoride.
