Oxidizing power of chlorine in aqueous solution can be determined by the parameters:$\frac{1}{2}{\text{Cl}}_2(g)\stackrel{\frac{1}{2}{\Delta }_{\text{diss}}H}{\to }\text{Cl}(g)\stackrel{{\Delta }_{\text{eg}}H}{\to }{\text{Cl}}^{-}(g)\stackrel{{\Delta }_{\text{hyd}}H}{\to }{\text{Cl}}^{-}(aq)$ Using the data:${\Delta }_{\text{diss}}{H}_{{\text{Cl}}_2}=240\text{kJ/mol}$${\Delta }_{\text{eg}}{H}_{\text{Cl}}=-349\text{kJ/mol}$${\Delta }_{\text{hyd}}{H}_{\text{Cl}}=-381\text{kJ/mol}$ The energy involved in the conversion of $\frac{1}{2}{\text{Cl}}_2(g)$ to ${\text{Cl}}^{-}(aq)$ will be:

1. A
   $+152\text{kJ/mol}$
2. B
   $-610\text{kJ/mol}$
3. C
   $-850\text{kJ/mol}$
4. D
   $+120\text{kJ/mol}$
