Answer 1

Answer #1

Correct option: Br₂.

Explanation:

Heat of vaporization,

$vap = Tb × Д.S1.ap$

where,

T_b = boiling point

$vap$ = entropy of vaporization

Among the options, only Br₂ is liquid at the room temperature. Hence, it has the highest boiling point among all the options.

As all the options are diatomic molecules, hence, their $vap$ is about the same.

Hence, Br₂ is predicted to have the highest heat of vaporization.
