Michael Faraday discovered benzene in the gas which was produced by destructive distillation of vegetable oil that is done in________________?
Correct answer: C. The absence of Oxygen
- A. The presence of Oxygen
- B. The presence of Hydrogen
- C. The absence of Oxygen
- D. The presence of excessive Oxygen
Explanation
Destructive distillation heats vegetable oil strongly in the absence of oxygen, causing decomposition into smaller substances including benzene without ordinary combustion. Students may choose the presence of oxygen because heating an organic material is incorrectly associated with burning.

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.
