Detailed explanation-1: -The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles-a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side). We say that the water molecule is electrically polar.

Detailed explanation-2: -When things are different at each end, we call them polar. Some molecules have positive and negative ends too, and when they do, we call them polar. If they don’t, we call them non-polar. Things that are polar can attract and repel each other (opposite charges attract, alike charges repel).

Detailed explanation-3: -Nonpolar molecules are molecules that do not have any electrical charges or partial charges. Nonpolar molecules are made of atoms that have a similar value of electronegativity. Electronegativity is the tendency of an atom to attract electrons.

Detailed explanation-4: -Non polar molecules are symmetric with no unshared electrons. Polar molecules are asymmetric, either containing lone pairs of electrons on a central atom or having atoms with different electronegativities bonded.

Detailed explanation-5: -A polar molecule is a molecule in which one end of the molecule is slightly positive, while the other end is slightly negative. A diatomic molecule that consists of a polar covalent bond, such as HF, is a polar molecule.
