Question

The boiling points of the elements helium, neon, argon, krypton, and xenon increase in that order. Which of the following statements accounts for this increase?

1. The London dispersion forces increase.
2. The hydrogen bonding increases.
3. The dipole-dipole forces increase.
4. The dipole-induced dipole forces increases.

Answer 1

The boiling point of noble gas increases as you go down the group because the London dispersion forces increase.
