Detailed explanation-1: -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.

Detailed explanation-2: -Polarity-Dipole Atoms, such as carbon and hydrogen, have a tendency to be more neutral or have partial positive charges. Electrons in a polar covalent bond are unequally shared between the two bonded atoms, which results in partial positive and negative charges.

Detailed explanation-3: -The opposite ends of a polar molecule have opposite charges. In a polar molecule electrons are shared unequally over the covalent bond. The more electronegative atom pulls the electrons closer to it, giving it a partial negative charge.

Detailed explanation-4: -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-5: -Like bonds, molecules can also be polar. In a polar molecule, electron density is unevenly distributed throughout the molecule, resulting in regions of partial negative charge and regions of partial positive charge.
