Vedclass · Answer

(C) $ICl$ is a polar molecule due to the electronegativity difference between $I$ and $Cl$ atoms,which leads to dipole-dipole interactions between its molecules.In contrast,$Br_2$ is a nonpolar molecule,and its intermolecular forces are limited to weak London dispersion forces.Therefore,the stronger intermolecular forces in $ICl$ result in a significantly higher boiling point compared to $Br_2$.

The molecular size of $ICl$ and $Br_2$ is approximately the same,but the $b.p.$ of $ICl$ is about $40 \ ^oC$ higher than that of $Br_2$. This is because:
