What is the dominant intermolecular force or bond that must be overcome in converting liquid CH3OH to a gas?
Dipole-dipole interaction
Covalent bonds
London dispersion force
Hydrogen bonding
As we learnt in
Hydrogen Bonding -
Attractive force which binds hydrogen atom of one molecule with the electronegative ( F, O, N ) atom of another molecule.
- wherein
It is of two type
1. Intermolecular and
2. Intramolecular
When H atom is bonded to F, O or N atoms which have high electronegativity, hydrogen bonding bonds the hydrogen atom of one molecule to F, O or N bond of another molecule.
Hydrogen bonding will be the dominant force while converting to gas.
