To which of the following classes of compounds does cyclohexane belong?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Alicyclic compound.
Cyclohexane is a saturated six-membered carbon ring with the molecular formula C₆H₁₂. It is classified as an alicyclic compound, which refers to cyclic compounds that are non-aromatic and can be either saturated or unsaturated. Cyclohexane is non-aromatic because it does not have conjugated π-electrons or follow Hückel’s rule.
Other options:
-
Benzenoid aromatic compound: Compounds containing a benzene ring; cyclohexane is saturated, so it is not aromatic.
-
Non-benzenoid aromatic compound: Aromatic compounds without a benzene ring; cyclohexane is non-aromatic.
-
Heterocyclic compound: Cyclic compounds containing atoms other than carbon in the ring; cyclohexane contains only carbon atoms.
