Question

What is the major fraction of high boiling fluorescent fraction of coal tar that produces cancer?

• A. 1,2-benzanthracene
• B. 3-methylcholanthracene
• C. 1,2-benzpyrene
• D. 9,10-dimethyl-1,2-benzanthracene

Answer 1

The correct option is A 1,2-benzanthracene

The major fraction of a high boiling fluorescent fraction of coal tar that produces cancer is 1,2-benzanthrcene.
Note:
Polynuclear hydrocarbons are carcinogenic in nature. People working with coal tar (prolonged exposure) suffer from skin cancer.
