$1-$ Bromopropane is reacted with reagents in List $I$ to give product in List $II$
| List$I-$ Reagent | List$II-$Product |
| $A$ $KOH (\text { alc) }$ | $I$ Nitrile |
| $B$ $KCN \text { (alc) }$ | $II$ Ester |
| $C$ $AgNO _2$ | $III$ Alkene |
| $D$ $H _3 CCOOAg$ | $IV$ Nitroalkane |

| $Cl_2(g) \rightarrow 2Cl(g),$ | $242.3\,kJ\,mol^{-1}$ |
| $I_2(g) \rightarrow 2I(g),$ | $151.0\,kJ\,mol^{-1}$ |
| $ICl(g) \rightarrow I(g)+Cl(g),$ | $211.3\,kJ\,mol^{-1}$ |
| $I_2(s) \rightarrow I_2(g),$ | $62.76\,kJ\,mol^{-1}$ |
Given that the standard states for iodine and chlorine are $I_2(s)$ and $Cl_2(g),$ the standard enthalpy of formation for $ICl(g)$ is : ............... $\mathrm{kJ\,mol}^{-1}$
