The comparatively high b.pt. of HF is due to

Options

  1. Ahigh reactivity of fluorine
  2. Bsmall size of hydrogen atom
  3. Cformation of hydrogen bonds and consequent association
  4. Dhigh IE of fluorine

Correct answer

C. formation of hydrogen bonds and consequent association

Step-by-step solution

Intermolecular hydrogen bonding is found in (HF) _ n due to higher electronegativity of fluorine atoms. Hydrogen bonding is helpful in the association of HF molecule, so HF is found in liquid form.
