Why is the boiling point of methane greater than that of neon?
Correct answer: C. Molecules of methane have stronger inter-molecular forces than those of neon.
- A. A molecule of methane has a greater mass than a molecule of neon.
- B. A molecule of methane has more electrons than a molecule of neon.
- C. Molecules of methane have stronger inter-molecular forces than those of neon.
- D. Molecules of methane from hydrogen bonds,but those of neon do not.
Explanation
Boiling point is only dependent on how strongly the given molecules are bonded, strong bonding leads to high B.P and weak bonding leading to low B.P. Methane has strong forces because methane has large surface area of contact and we know larger the surface area stronger is bond, in contrast neon has smaller surface area.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
