Aromatic compounds burn with sooty flame because:
Correct answer: C. They have high percentage of carbon
- A. They have high percentage of hydrogen
- B. They have a ring structure
- C. They have high percentage of carbon
- D. They resist reaction with air
Explanation
The aromatic compound displays aromaticity. They burn with a strong sooty yellow flame. A "sooty flame" indicates that incomplete combustion is occurring and the reason for this flame is the high percentage of carbon content. The carbon-hydrogen ratio is high in aromatic compounds.

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.
