Discuss the shape of CO_(2) molecule on the basis of hybridisation.

In order to explain the characteristic geometrical shapes of polyatomic molecules, Pauling introduced the concept of hybridisation. The orbitals undergoing hybridisation should have nearly same energy. There are various types of hybridisations involving s, p and d - type of orbitals. The type of hybridisation gives the characteristic shape of the molecular or ion. Which molecule does not have the same type of hybridisation as P has in PF_(5) ?

Assertion : Molecular having different hybridisation can have same shape. Reason :The shape of a molecule does not depend on the hybridisation but it depends on the energy factor.
