Question

We know that the ionic bonds are more stronger than the covalent bond,so why it is slightly complicated to dissolve the covalent bonded compounds?

Answer 1

Covalent molecules are attracted to each other by various intermolecular forces such as H-bonds, dipole-dipole forces, and London dispersion forces. These are strong intermolecular forces. Hence, covalently bond compounds do not readily dissolve.

For example, hexane, C₆H₁₄, does not dissolve in water. Its molecules have little attraction to each other.
