Detailed explanation-1: -Water is a polar molecule due to the unequal distribution of its electron density. Because there is a difference in electronegativity between hydrogen and oxygen, this shows that water is a polar molecule. Water is known as the universal solvent because it can dissolve more compounds than any other liquid.
Detailed explanation-2: -Thus, when a molecule contains polar bonds as such, the molecule is said to be polar. This is why a water molecule is polar, and this uneven distribution of electron density enables the oxygen from one water molecule to attract to the hydrogen atom of another and form bonds called hydrogen bonds.
Detailed explanation-3: -Oxygen atoms are bigger than hydrogen atoms. Very simply, think of oxygen as a “bully” who keeps hydrogen’s single electron. As a result, the water molecule is “polar”, meaning the molecule has an unequal distribution of charge.
