MCQ - 4-2190

Question:

Which of the following is the reasons for the statement: "although benzene is highly unsaturated, normally it

does not undergo addition reaction".
It has no free electrons
Strong nuclear attraction prevents π electrons to go under any reaction.
It has no free electrons
Alternate single and double bonds in benzene inhibit further reactions.

Correct Answer: C

Explanation:

Benzene is an aromatic compound and is stabilized due to resonance or delocalization of π electrons. When it undergoes addition reactions, it will lose resonance stabilization. Hence it resists electrophilic additions to double bonds in it. Rather, it prefers to undergo electrophilic substitution reactions.
