Assertion : In `CO_(2)` molecule C atoms undergoes `sp^(2)` hybridisation
Reason : `CO_(2)` molecule has net dipole moment.

Answer

D

Explanation

In `CO_(2)` molecule, carbon atom undergoes sp hybridisation.
`:ddot(O) = C = ddot(O) :`
The two sp hybridised orbitals of C-atom overlap with two p-orbitals of O-atoms to make `2 sigma` bonds while other tow electons of C-atoms are involved in `p pi = p pi` bonding with oxygen atom. Hence, it is linear is shape with equal C - O bond lengths and no dipole moment.
