Question
The intermolecular forces of attraction (i.e., H-bonding and van der Waals' forces) exist among polar and non-polar species which affect melting point, boiling point, solubility and viscosity of covalent compounds :
π‘ Solution & Explanation
Step 1: Understand that the potential energy of a bonding system reaches a minimum at the optimum internuclear distance (bond length), balancing attractions and repulsions. Step 2: If the internuclear distance is decreased below this optimum distance, the nuclei and core electron clouds are forced too close together. Step 3: This leads to a massive, steep increase in potential energy due to the sharp increase in electrostatic repulsions between the positively charged nuclei and between the negatively charged electron clouds.
