What is the dominant intermolecular force or bond that must be overcome in converting liquid CH ₃ OH to a gas ?

Options

  1. AHydrogen bonding
  2. BDipole-dipole interaction
  3. CCovalent bonds
  4. DLondon dispersion force

Correct answer

A. Hydrogen bonding

Step-by-step solution

Key Idea When H atom is directly linked with N or O , or F , inter or interamolecular H -bonding is formed. In between CH ₃ OH molecules intermolecular H-bonding exist. Hence, it is the intermolecular H-bonding that must be overcome in converting liquid CH ₃ OH to gas.
