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: -Nonpolar molecules are molecules that do not have any electrical charges or partial charges. Nonpolar molecules are made of atoms that have a similar value of electronegativity. Electronegativity is the tendency of an atom to attract electrons.

Detailed explanation-3: -Answer and Explanation: Water is the most polar molecule among the given molecules. This is because of the high electronegativity difference between the atoms of water (hydrogen and oxygen) and their hydrogen bonding.
