Covalent - equal sharing of generally one pair of electrons (e.g. H2 hydrogen molecule)
Polar covalent- ubequal sharing - the more electronegative element "attracts " the electrons in the bond towards it causing the formation of a small negative charge (and a small compensating positive charge on the less electronegative atom) example HCl, hydrogen chloride molecule
A hydrogen bond is a weak electrostatic bond invoving a hydrogen atom covakently bonded to one atom attracted to a very electrnegative atom. (Example is water, H2O)
Both Dipole-Dipole Interactions and Hydrogen Bondings are used to describe the attraction between molecules. For Dipole-Dipole interactions to occur the molecules in the compound must be polar. Both Dipole-Dipole and Hydrogen Bondings require that the molecule have a electronegative atom to make up a negative region and a less electronegative atom to become the positive region. The negative region on a molecule attracts the positive region of another molecule. This affects the melting and boiling points of a compound. Hydogen Bondin occur when a hydrogen atom is the positive region and is bonded to a strong electronegative atom like Fluorine, Oxygen and Nitrogen. Being bonded to a strong electronegative atom will make the hydrogen become strongly positively charged and the other electronegative atom stronly negatively charged.

Just wryte the definition of dipole attraction and an ionic bond. That'll be your dyfferences
dipole-dipole occurs between polar molecules ion-dipole occurs between mixtures of ionic compounds and polar compounds
Dipole-Dipole forces
Dispersion forces are formed between two non-polar molecules. These molecules form temporary dipoles. This creates a weak force. Dipole Dipole forces have a permanent dipole. That is the basic explanation
Dipole-dipole The attraction between two dipoles.
Intermolecular attraction
It has dispersion forces, dipole dipole forces ,and hydrogen bonding. Source: I'm a chemistry professor

Intermolecular attraction
Dipole-dipole attraction and van der Waals forces.
The force of attraction between unlike molecules is known as intermolecular attraction or van der Waals forces. These forces can be categorized as dipole-dipole interactions, hydrogen bonding, or London dispersion forces. The attraction between the surfaces of different contacting bodies is called adhesion and is typically due to intermolecular forces such as van der Waals forces or electrostatic interactions.
An ion induces dipole forces by inducing a dipole in an atom or molecule with no dipole. An ion-induced dipole attraction is a weak attraction.
