What  is the dominant intermolecular force or bond that must be overcome in converting liquid CH3OH to a gas?

  • Hydrogen bonding

  • Dipole-dipole interaction

  • Covalent bonds

  • London dispersion force

Answer

A.

Hydrogen bonding

When H atom is directly linked with N or O, or F, inter or intramolecular H - bonding is formed.
In between CH3OH molecules, intermolecular H-bonding exists. 


Hence, it is the intermolecular H - bonding that must be overcome in converting liquid CH3OH to gas.
