Which one of the following is the correct order of interactions ?

Options

A. Covalent lt hydrogen bonding lt van der Waal's lt dipole-dipole
B. van der Waals' lt hydrogen bonding lt dipole-dipole lt covalent
C. van der Waals' lt dipole dipole lt hydrogen bonding lt covalent
D. dipole dipole lt van der Waals' lt hydrogen bonding lt covalent

Answer

B

Explanation

The van der Waals' force are weakest forces and covalent bond is strongest, so the order of interactions is van der Waals' lt H-bonding lt dipole -dipole lt covalent.
