Which of the following is correct statement?

Question

Which of the following is correct statement? (A) F2 has higher dissociation energy than Cl2 (B) F has higher electron affinity than Cl (C) HF is stronger acid than HCl (D) Boiling point increases down the group in halogens

Tardigrade Admin · Accepted Answer

Here only statement D is correct and rest are incorrect as

A .

bond dissociation energy of

F_{2}

is less than that of

C l_{2}

B .

Cl has higher E.A. than fluorine.

C .

HF is weaker acid than HCl, due to higher bond energy.

D .

On moving down the group boiling point increases as with the increase of molecular weight van der Waal's force increases.

Q. Which of the following is correct statement?

$F_{2}$ has higher dissociation energy than $C l_{2}$

F has higher electron affinity than Cl

HF is stronger acid than HCl

Boiling point increases down the group in halogens
