MCQ

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

$\pi$-electrons of benzene ring are delocalised.

Explanation:

$\pi$-electrons of the benzene ring are delocalised.

There are delocalised π-electrons above and below the plane of the ring. The presence of the delocalised $\pi$-electrons makes benzene particularly stable.

Benzene resists addition reactions because that would involve breaking the delocalisation and losing that stability.
