Molecular size of ICI and Br2 is nearly ...

Molecular size of `ICI` and `Br_2` is nearly same but `b.pt.` of ` ICI` is about ` 40^@` higher than `BR_2` . This is due to :

A

`I- Cl` bond is stronger than `Br -Br` bond

B

ionisation enrgy of `I` gt ionisation enrgy of Br

C

`ICl` is polar whereas `Br_2` is non-plar

D

size of I is larger than `Br`

Text Solution

Verified by Experts

The correct Answer is:
C
Polarity in a molecule give rise to an increase in forces of attraction among molecules and thus more becomes boiling point .
