Question

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

Answer 1

shape of H2O molecule is bent because of the formation of hydrogen bond in it.

Answer 2

Answer :

In CO2, there are two C=O bonds. Each C=O bond is a polar bond.

The net dipole moment of C02 molecule is zero. This is possible only if CO2 is a linear molecule. (O=C=O). The bond dipoles of two C=O bonds cancel the moment of each other.

Whereas, H2O molecule has a net dipole moment (1.84 D). H2O molecule has a bent structure because here the O—H bonds are oriented at an angle of 104.5° and do not cancel the bond moments of each other
