Question

List the following molecules in order of increasing boiling point: Br2, Cl2, F2, I2.

Answer 1

Answer:

1. None of these have hydrogen bonding.

2. None of these have dipoles.

3. Bigger molecules will have stronger London dispersion forces. So I2 has the strongest forces,

and F2 will have the weakest. Correspondingly, I2 will have the highest boiling point and F2 will have the lowest boiling point.

Answer: F2, Cl2, Br2, I2

Explanation:

Answer 2

Answer:

The molecules in order of increasing boiling point : F2>Cl2>Br2>l2.
