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: -polar bond: a covalent bond that has opposite partial charges on each side (one side partially positive and one side partially negative), because of unequal sharing of electrons. For example: The bond between H and Cl in the H-Cl molecule is a polar bond.

Detailed explanation-3: -Water is a Polar Covalent Molecule 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-4: -Electrons in a polar covalent bond are unequally shared between the two bonded atoms, which results in partial positive and negative charges. The separation of the partial charges creates a dipole. The word dipole means two poles: the separated partial positive and negative charges.

Detailed explanation-5: -A polar bond is a bond in which electrons are shared unequally, resulting in a slightly positive end and a slightly negative end. A nonpolar molecule is a molecule that does not have oppositely charged ends.
