SSC MTS EXAM

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: -Explanation: Water (H2O) is a polar molecule because the electrons of the hydrogen atoms get “pulled” towards the electrons of the oxygen atom. This makes a region of positive charge on the hydrogen atoms and the negative charge on the other end of the molecule, which is the oxygen atom.

Detailed explanation-3: -If oxygen and hydrogen had equal electronegativity, then the shared electrons would be pulled equally close to both atoms creating a non polar covalent bond rather than a polar covalent bond. There would be an equal distribution of charges, so water would no longer be a polar molecule.
