The hydrocarbon which has three linear fused benzene rings?
Correct answer: D. Anthracene
- A. Phenanthrene
- B. Triphenylmethane
- C. Diphenyl ether
- D. Anthracene
Explanation
Anthracene consists of three linearly fused benzene rings, making it a polycyclic aromatic hydrocarbon. This structure allows for unique chemical properties and reactivity compared to other hydrocarbons. In contrast, Phenanthrene also has three fused rings, but they are arranged in a non-linear configuration, disqualifying it from being the correct answer. Triphenylmethane features three benzene rings attached to a central carbon, but these rings are not fused, thus they do not meet the criteria of the question. Lastly, Diphenyl ether has two distinct benzene rings linked by an oxygen atom, which keeps them isolated rather than fused.

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.
