Question

The average bond length in C-C in benzene (C6H6) is between single and double bond lengths. This is due to which of the following effect?

1. Due to its refractive index2. Due to the possession of resonance3. Due to its H atoms4. Due to the H-bonds

Answer 1

2. Due to the possession of resonance

Step-by-step explanation:

In the benzene ring, the electrons that results in the bonds between the carbon atoms are delocalized. That is, they do not belong to a specific carbon atom. It is this unique feature that enables them to have a bond length between single and double bond lengths.

This feature is as a result of resonance.

The correct option is 2.
