Select the true statement about benzene among the following

1. Because of unsaturation benzene easily undergoes addition
2. There are two types of C–C bonds in benzene molecule
3. There is cyclic delocalisation of pi-electrons in benzene
4. Monosubstitution of benzene gives three isomeric products

Correct answer: There is cyclic delocalisation of pi-electrons in benzene

Solution

Benzene exhibits cyclic delocalization of pi-electrons, which is responsible for its aromaticity and stability. This delocalization makes it undergo substitution reactions rather than addition reactions. All C–C bonds in benzene are equivalent due to resonance, and monosubstitution yields only one product.
