Question

Molecular size of ${\rm{ICl}}$ and ${\rm{B}}{{\rm{r}}_2}$ is nearly same, but boiling point of ${\rm{ICl}}$ is about $40^\circ C$ higher than ${\rm{B}}{{\rm{r}}_2}$. This might be due to:

Accepted Answer

${\rm{ICl}}$ is polar where as ${\rm{B}}{{\rm{r}}_2}$ is non-polar

Answer

${\rm{I - Cl}}$ bond is stronger than ${\rm{Br}} - {\rm{Br}}$ bond

Answer

Ionisation energy of ${\rm{I}} < $ ionisation energy of Br

Answer

The size of ${\rm{I}} > $ size of ${\rm{Br}}$
