Expert Answer:

Polar covalent bond: When the two bonding atoms have difference ion their electronegativites, theat covant bond is called as polar covalent bond. The shared electrons have tendency to shift towards more electronegative atom. Hence there will be a slight negative charge on more electronegative atom and sight positive charge on less electronegative atom.
Coordinate covalent bond: It is dipolar bond, also known as a dative covalent bond or coordinate bond is a kind of 2-center, 2-electron covalent bond in which the two electrons derive from the same atom.
Non-polar covalent bond:  It is a covalent bond where the electrons are shared equally between the two atoms.
For example, the covalent bond between two Cl atoms in Cl2. The electronegativity of both the bonding atoms is similar, hence there is equal sharing of electrons.
