The boiling points of diatomic halogens are compared in the table.

Question

Boiling Points of Diatomic Halogens
Molecule Boiling Point
F2 −188 °C
Cl2 −34 °C
Br2 59 °C
I2 184 °C

Diatomic bromine has weaker intermolecular forces than diatomic fluorine.
True
False

Answer 1

False.

Diatomic bromine (Br₂) has a higher boiling point (59 °C) than diatomic fluorine (F₂) (−188 °C), indicating that Br₂ has stronger intermolecular forces than F₂. The boiling point of a substance is related to the strength of its intermolecular forces: stronger forces result in higher boiling points. In this case, the intermolecular forces in Br₂ (which are primarily London dispersion forces) are stronger due to its larger molecular size and greater number of electrons compared to F₂.
