Benzene (C6H6) contains a six-membered ring with three alternate double bonds. Compounds having this characteristic unit are called:
ASaturated compounds
BAliphatic compounds
CAromatic compounds
DBranched compounds
Answer & Solution
Correct answer: C. Aromatic compounds
1. Benzene is a cyclic hydrocarbon with a six-membered ring.
2. Its ring carries three alternate double bonds.
3. Compounds containing this characteristic ring unit are called aromatic compounds.
4. Rule out A: double bonds make it unsaturated, so 'saturated' is wrong.
5. Rule out B: 'aliphatic' means open-chain, but benzene is a ring.
6. Rule out D: 'branched' describes a side chain, not benzene's closed ring.
