Question

Co2 and h2o are triatomic molecule. the shape of h2o is bent or v shape while that co2 is linear. expalin how?

Answer 1

this is because of the bond formed h2o has single bond and co2 has carbon double bond

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.
