The correct answer is: ✅ A. Triphenylmethane Explanation An isolated ring means that the aromatic rings are not fused together. They are connected by single bonds or through another atom. A. Triphenylmethane (✔ Correct) Structure: Three separate benzene rings attached to one central carbon (CH). The benzene rings are isolated (not fused). Each benzene ring is aromatic. Therefore, it is an aromatic hydrocarbon with isolated rings. B. Phenanthrene (✘ Incorrect) It consists of three fused benzene rings. It is aromatic, but the rings are fused, not isolated. MDCAT Tip Isolated aromatic rings → Rings are connected by single bonds or carbon atoms (e.g., Triphenylmethane, Biphenyl). Fused aromatic rings → Rings share common sides (e.g., Naphthalene, Anthracene, Phenanthrene). Answer: ✅ A. Triphenylmethane I also got this answer from chatgpt
