Problem

The molecular size of

\text{ICl}

and

\text{Br}_2

is approximately same, but b.p. if

\text{ICl}

is about

40^\circ\text{C}

higher than that of

\text{Br}_2

. It is because : (1)

\text{ICl}

bond is stronger than

\text{Br}-\text{Br}

bond (2)

\text{IE}

of iodine

<

\text{IE}

of bromine (3)

\text{ICl}

is polar while

\text{Br}_2

is nonpolar (4)

\text{I}

has larger size than

\text{Br}
