Options:
  • A It forms only one type of monosubstituted product
  • B There are three carbon-carbon single bonds and three carbon-carbon double bonds
  • C Heat of hydrogenation of benzene is less than its theoretical value
  • D The bond angle between carbon-carbon bonds is $120^{\circ}$

The correct answer is: There are three carbon-carbon single bonds and three carbon-carbon double bonds
The Benzene has \(120^{\circ}\) bond angle.
The more heat released, the more negative the value. Benzene releases less heat (has a lower heat of hydrogenation) because of its aromatic properties which gives it remarkable stability.
Benzene does not have 3 single and 3 double bonds. All bonds are partially double bonds due to resonance.
