Question

Molecular size of ICl and Br 2 is nearly the same, but boiling point of ICl is about 40° C higher than Br 2. This might be due to (A) I-Cl bond is stronger than Br - Br bond (B) IE of I < IE of Br (C) ICl is polar whereas Br 2 is non-polar (D) The size of I > size of Br.

Polarity in a molecule gives rise to an increase in force of attraction among molecules and, thus, have higher boiling point.

Q. Molecular size of $I Cl$ and $B r_{2}$ is nearly the same, but boiling point of $I Cl$ is about $4 0^{\circ} C$ higher than $B r_{2}$ . This might be due to

I-Cl bond is stronger than Br - Br bond

IE of I $<$ IE of Br

ICl is polar whereas $B r_{2}$ is non-polar

The size of I $>$ size of Br.

Q. Molecular size of ICl and Br2​ is nearly the same, but boiling point of ICl is about 40∘C higher than Br2​. This might be due to

I-Cl bond is stronger than Br - Br bond

IE of I < IE of Br

ICl is polar whereas Br2​ is non-polar

The size of I > size of Br.
