Expert Answer
'Polar' means the separation of the positive and the negative charge.
A bond between 2 nonmetal atoms that have different electronegativities and therefore have unequal sharing of the bonding electron pair. Therefore the covalent bond between them is considered as polar. Example: HCl
'Non-polar' means the symmetrical distribution of charge such that there is no separation of charges.
A bond between 2 nonmetal atoms that have the same electronegativity and therefore have equal sharing of the bonding electron pair. Therefore the covalent bond between them is considered nonpolar. Example: Homonuclear molecules like Cl2, H2.
