Question

What is conjugated planar ring system with delocalized pi electron clouds?

Answer 1

Dear Student,

The given statement is the condition for the aromaticity. If the system is a planar structure, a ring in which the pi-electrons are delocalised then, it is said to be aromatic. If we consider benzene ring. Benzene ring is a planar structure and it contains single and double bonds at alternate positions. The double bond is made up of one sigma and one pi-bond. The pi-bond is out of the plane. In benzene, when the double bonds are at alternate positions, then due to this arrangement, there is a formation of pi-electron cloud. This is called delocalisation. So, benzene is a conjugated planar ring with delocalised pi-electron cloud.
