с
dispersion force < dipole - dipole < hydrogen bonding < covalent
D
Dipole-dipole < dispersion force < hydrogen bonding <covalent.​

Answer 1

Answer:

b) london dispersion force < hydrogen bonding < dipole - dipole interactions < covalent bonding

Explanation:

Intramolecular forces are stronger than intermolecular forces. This explains why covalent bonding is strongest of all the given interactions.

Amongst the intermolecular interactions, Dipole- Dipole interactions are the strongest intermolecular force of attraction. They occur between the positively charged and negatively charged molecules.

Hydrogen bonding is the second strongest intermolecular interaction and occurs between H atom and O, N or F atom.

London dispersion forces( otherwise, Van der Waals forces) are the weakest intermolecular interaction and occurs between all the molecules, whether ionic or covalent, polar or non-polar.
