Question

Which one of these is not true for benzene?

• 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 ${120}^{\circ }$

Answer 1

Answer: (B)

There are three carbon -carbon single bonds and three carbon-carbon double bonds

The Benzene has ${120}^0$ 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.
Thus option B state the wrong statement about Benzene. Hence, B is the correct option.
