Cyclopentene is a _________?
Correct answer: B. Alicyclic
- A. Aromatic
- B. Alicyclic
- C. Aliphatic
- D. None of These
Explanation
Cyclopentene is a non-aromatic cyclic hydrocarbon, so it is classified as alicyclic. The likely wrong choice is aliphatic, since aliphatic can be used broadly for non-aromatic compounds, but alicyclic is the more specific term for a non-aromatic ring compound.

About Alkenes
Alkenes are unsaturated hydrocarbons containing a carbon-carbon double bond with sigma and pi components and restricted rotation. Their reactions include electrophilic addition of hydrogen, halogens, hydrogen halides and water, with Markovnikov orientation, oxidation, combustion and polymerisation, while their preparation commonly involves elimination from alkyl halides or alcohols.
