Although both co2 and h2o are triatomic molecules the shape of H2O molecule is bent while that of seo2 is linear explain this on the basis of dipole moment
Answers
Dipole moment is the product of the magnitude of the positive or negative charge (q) & the distance (d) between the charges,i.e
μ = q x d.
The SI unit is coulomb metre.The molecule with symmetrical & linear geometries have zero dipole moment because they are vector in nature & the dipole of different bonds cancel with one another. CO2 is symmetrical & has dipole moment 0.Therefore it will have a linear shape with bond angle 180°.
Resultant μ = 0 D
H2O is a unsymmetrical molecule & bent geometries, the geometries have specific dipole moment (1.84D) because the bond polarities do not cancel each other. Therefore H2O will have a bent structure with bond angle 104°.
Answer:this is due to the difference in cancelling out of their bond dipole ..
Explanation:due to linear structure of CO2 each bond dipole of c-0 get cancelled with with each other, and the value comes to be zero. Hence CO2 is a non Polar molecules.

In case of H2o,
Due to bent structure of water each bond dipole of o-H don't cancelled with each other .. And the valve becomes greater than zero i.e 1.83D .
Hence H2o is a polar dipole.
