Main source of aromatic compound is:
Correct answer: B. Coal-tar
- A. Petroleum
- B. Coal-tar
- C. Living organism
- D. Dead marine animals
Explanation
Aromatic compounds are cyclic compounds in which all ring atoms participate in a network of π bonds, resulting in unusual stability. Aromatic compounds are less reactive than alkenes, making them useful industrial solvents for nonpolar compounds. Aromatic compounds are produced from petroleum and coal tar.

About Benzene and Aromatic Compounds
Benzene has a planar ring of delocalised π electrons, giving aromatic stability and equal carbon-carbon bond lengths. The topic covers resonance, electrophilic substitution reactions such as nitration, halogenation, sulphonation and Friedel-Crafts reactions, along with substituent effects and the distinction between substitution in benzene and addition in ordinary alkenes.
