Which of the following is correct statement ?

Options

A. `F_(2)` has higher dissociation energy than `Cl_(2)`
B. F has higher electron affinity than Cl
C. `HF` is stronger acid than `HCl`
D. Boiling point increases down the group in halogens.

Answer

4

Explanation

`(1)-` Bond dissociation energy of `F_(2)` is less than that of `Cl_(2)`
`(2)-` Cl has higher E.A. than fluorine.
`(3)-HF` is weaker acid than HCl, due to higher bond energy.
