Total number of sp2 hybrid orbitals of all the carbon atoms in benzene are:
Correct answer: D. 18
- A. 3
- B. 6
- C. 12
- D. 18
Explanation
Each of the six carbon atoms in a benzene ring is sp² hybridized. Each sp² hybridized atom has three sp² hybrid orbitals. Therefore, the total number of hybrid orbitals in the molecule is 6 carbon atoms x 3 hybrid orbitals/atom = 18.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
