JEE Main Chemistry question

For the interactions (I) Covalent bond, (II) van der Waals' forces, (III) Hydrogen bonding, (IV) Dipole-dipole interaction, which represents the correct order of increasing stability?

(A)(I) < (III) < (II) < (IV)
(B)(II) < (III) < (IV) < (I)
(C)(II) < (IV) < (III) < (I)Correct
(D)(IV) < (II) < (III) < (I)

Answer: (C)

Solution

Among these interactions, van der Waals' forces (II) are the weakest (purely induced, instantaneous dipole attractions). Simple dipole-dipole interactions (IV) between molecules with permanent dipoles are somewhat stronger than van der Waals' forces. Hydrogen bonding (III) is itself a special, unusually strong case of
