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

  • Option 1)

    Dipole-dipole interaction

  • Option 2)

    Covalent bonds 

  • Option 3)

    London dispersion force

  • Option 4)

    Hydrogen bonding

 

Answers (1)

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 CH_{3}OH(liq.) to gas.


Option 1)

Dipole-dipole interaction

This option is incorrect.

Option 2)

Covalent bonds 

This option is incorrect.

Option 3)

London dispersion force

This option is incorrect.

Option 4)

Hydrogen bonding

This option is correct.
