What are the necessary conditions for any compound to show aromaticaly?

Text Solution

Verified by Experts

(i) The system (or species) must be planar (ii) It should be cyclic
(iii) It must contain (4n+2) delocalised `pi` electrons where n is an integer (including Zero). Thus conjugated, planar cyclic systems containing 2,6,10,14…. Delocalised `pi` electrons will be aromatic
