Ans: Option (iii)
The dipole moment of the molecule depends on the difference in the electronegativity of the atoms present in the structure. The dipole moment of CO2 is 0, HI is 0.38, H2O is 1.84 and SO2 is 1.62.
As the oxygen atom is highly electronegative and hydrogen is least electronegative, the difference in electronegativity will be the highest for water molecules. Therefore, water molecules will have the highest dipole moment.

The three types of chemical bonds are - ionic, metallic and covalent bonds. When the electrons transfer between the atoms, they form the Ionic bonds by producing charged ions that are attracted to each other. When atoms share electrons, covalent bonds are created. When metal atoms share a sea of delocalized electrons, metallic bonds get created.
