Question

Which of the following statements about the chemical properties of benzene is correct?
It readily undergoes substitution reactions but not addition reactions.
It does not undergo either substitution reactions or addition reactions.
It readily undergoes both substitution reactions and addition reactions
It readily undergoes addition reactions but not substitution reactions.

Answer 1

Answer:

It readily undergoes substitution reaction but not

addition reactions.

reason: pi- electrons are dispersed

around six C- atoms instead of any two C-atoms

Answer 2

Answer:

It readily undergoes substitution reactions but not addition reactions.

The $\pi$-electrons in benzene are delocalized, making the structure more stable. The term "resonance" refers to the delocalization of an electron. As a result of resonance stabilization, benzene does not give rise to addition reactions.

Benzene has three double bonds, which indicates that it is unsaturated, and so inspires us to do an addition reaction.

However, this is absolutely incorrect. Due to resonance, the three double bonds of a benzene ring are conjugated and thereby stabilize the benzene ring.

As a result, the benzene ring is extremely stable, and addition reactions on it can be avoided.

As a result, substitution reactions are preferable to addition reactions.
