Which of the following does not have sp2 hybridized orbital?
Correct answer: B. Acetonitrile
- A. Acetone
- B. Acetonitrile
- C. Acetic acid
- D. Acetamide
Explanation
Acetonitrile has a nitrile group (-CN), where the carbon is sp hybridized. The nitrogen is also sp hybridized. Since the carbon in the nitrile group is sp hybridized, it does not have sp2 hybridized orbitals.

About Hybridization
Hybridization explains bonding by combining atomic orbitals to form equivalent hybrid orbitals with definite geometries. Coverage includes sp, sp², sp³, sp³d and sp³d² hybridization, their shapes and bond angles, and the relation of sigma and pi bonds to molecular structure.
