Question

H2O has dipole moment whereas co2 does not why​

Answer 1

Explanation:

Becoz The shape of Co2 Is linear, ..so charge becomes cancel....☺✌

Answer 2

• In CO₂ molecule, the central carbon atom is sp - hybridised and so CO₂ is a linear molecule. For this type of structure, the two oppositely oriented C=O bond moments cancel out each other. Because of this, CO₂ is a non-polar molecule, i.e., it has no net dipole moment.

• In H₂O molecule, the oxygen atom is sp³- hybridised. So, in this molecule, the two unshared electron pairs and the two O-H bonds are arranged tetrahedrally and the actual shape of the molecule is angular. Because of such geometrical shape, water molecule possesses considerable dipole moment, i.e., it is a polar molecule.
