Question

Although benzene is highly unsaturated it does not undergo addition reactions. The explanation of this can be suggested as
A. `pi`-electrons of benzene ring are delocalised
B. since `pi`-electrons are present inside the ring, addition cannot take place
C. cyclic structures do not show addition reactions
D. benzene is not a reactive compound.

Answer 1

Correct Answer - A
`pi`-electrons of benzene ring are delocalised throughout the molecule. This makes the molecule very stable. The stability resists breaking of double bond for addition.
