Consider the b.pr. of `Br_2` and ICl. The b.pt. of `Br_2`

A

is equal to the b.pt. of IC l

B

is less than the b.pt. of IC l

C

is more than the b.pt.of IC l

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
B
IC l is a polar molecule due to electronegativity difference of I and Cl. On the other hand , `Br_2` is a non polar molecule, Due to greater

  • 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`

  • The molecular size of Icl and Br_(2) is approximately same, but b.p. if Icl is about 40^(@)C higher than that of Br_(2) . It is because :
