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).

Detailed explanation-2: -A molecule that is slightly positive on one end and slightly negative on the opposite end is a polar molecule. Polar molecules are the result of polar bonds and asymmetry in molecular geometry. Polar bonds result when electrons are not shared equally between the two bonded atoms.

Detailed explanation-3: -A molecule with a partial positive charge on one side of the molecule and a partial negative charge on the other side of the molecule is called a polar molecule. Water is an example of a polar molecule.

Detailed explanation-4: -Polar covalent compounds have molecules with a partial negative charge on one side and a partial positive charge on the other side. This occurs because the compounds contain polar bonds. In a polar bond, one atom attracts the shared electrons more strongly than the other atom does.

Detailed explanation-5: -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).
