What do you understand by a lone pair of electrons?

The pair of electrons that are left in the valence shell without forming covalent bonds are known as lone pairs of electrons. They affect the shape of the molecule and sometimes help in the formation of other molecules.

Give a reason for the following: Ionic compounds have a high melting point.

Ionic compounds have high melting point because, there is a strong electrostatic force of attraction between the oppositely charged ions, that is, there is a strong electrostatic force of attraction between the cation and the anion.
