On the basis of molecular orbital treatment of various aromatic compound, it has been observed that an aromatic compound must fulfil the following theoritical requirements It must have an uninterrupted cyclic cloud of pi-electrons above and below the plane of the molecule (often called as pi-cloud). Let us look what does this mean? (i). for the pi-cloud to be cyclic, the molecule must be cyclic. (ii). For the pi-cloud to be uninterrupted, every atom int he ring must have a p-orbital iii). for the pi-cloud to be fomred, each p-orbital must be able to overlap with the p-orbitals on either side of it. therefore, the molecule must be planar. Q.
