Question

Select the true statement about benzene amongst the following

• A. Because of unsaturation benzene easily undergoes addition
• B. There are two types of C-C bonds in benzene molecule
• C. There is cyclic delocalisation in pi bonds in benzene
• D. Mono substitution of benzene gives 3 isomeric products.

Answer 1

Answer: (C)

There is cyclic delocalisation in pi bonds in benzene

In benzene molecule,all$C-C$ bond length are equal,it does not give addition product but there is a cyclic delocalisation of $\pi$ bonds in benzene ring Mono-substitution of benzene gives single isomeric product.
