An energy diagram for the three molecular orbitals of the cyclopropenyl system is to be drawn. How these three molecular orbitals are occupied in the cyclopropenyl anion, cation and radical is to be indicated. Which among the three is aromatic is also to be stated. Concept introduction: The numberof molecular orbitals formed is equal to the number of orbitals overlapping. The available orbitals are filled by the electrons in the increasing order of their energies.Each moleclar orbital can accommodate two electrons with opposite spin. Electrons occupy the orbitals individually first before they get paired in the same orbital. The cyclopropenyl cation has two electrons to be filled in molecular orbitals. The cyclopropenyl radical has three electrons to be filled in molecular orbitals. The cycloproenyl anion has four electrons to be filled in molecular orbitals. To draw: The relative energy levels of the three Ï€ molecular orbitals of the cyclopropenyl cation, radical and anion. To indicate: How the three Ï€ molecular orbitals are filled in cyclopropenyl cation, radical and anion. To state: Which of these three are aromatic.

Question

Definition Definition Rule that estimates whether a given organic planar ring structure will show an aromatic property. A cyclic ring molecule is said to follow Hückel’s rule if the л-electrons count in a molecule is [4n+2], where n stands for a positive numerical value. It is also called the [4n+2] rule. Hückel's rule, sometimes referred to as the aromaticity rule, is one but not the only criteria to judge a molecule for aromaticity.
