JEE Main Chemistry question

The predominant intermolecular force in hydrogen fluoride is due to

(A)Dipole-induced dipole interaction
(B)Dipole-dipole interaction
(C)Hydrogen bond interactionCorrect
(D)Dispersion interaction

Answer: (C)

Solution

In HF, the hydrogen atom is directly bonded to the highly electronegative fluorine atom, creating a strong permanent dipole; the small, exposed hydrogen atom can then interact strongly with the lone pair of a neighbouring fluorine atom,
