Detailed explanation-1: -The shape of the water molecule is bent and this shape means that the positive charge of the hydrogen atoms is on the other side of the molecule and most of the negative charge from the oxygen on the other side of the molecule. Hence, we can say that the water molecule is polar and thus statement 1 is correct.

Detailed explanation-2: -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-3: -Water is a molecule that is formed when one atom of oxygen bonds covalently with two atoms of hydrogen, to make H2O H 2 O .

Detailed explanation-4: -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-5: -Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen, and a bent overall structure. This is because oxygen is more electronegative, meaning that it is better than hydrogen at attracting electrons. Water is an excellent solvent.
