Several fused polynuclear hydrocarbons are known to be highly toxic and carcinogenic, often formed d — Aromatic Hydrocarbons Chemistry Question

💡 Solution & Explanation

Fused polynuclear hydrocarbons like 1,2-benzpyrene, 3-methylcholanthrene, and 1,2,5,6-dibenzanthracene are highly toxic and carcinogenic. They are typically formed during the incomplete combustion of tobacco, coal, or petroleum, and undergo biochemical changes in the human body that ultimately damage DNA. Naphthalene, diphenylmethane, and azulene do not possess this extreme carcinogenic profile.
