WebDrawing out these molecular orbitals would be a little bit too complicated for this video. So checkout your textbook for some nice diagrams of the six molecular orbitals of benzene. However, it is important to understand those six molecular orbitals in terms of their relative energy levels. And the simplest way to do that is to draw a frost circle.

Question: a. ) The following molecule is aromatic. … WebThe compound is the prototypical antiaromatic hydrocarbon with 4 π-electrons. It is the smallest [ n ]- annulene ( [4]-annulene). Its rectangular structure is the result of the Jahn–Teller effect, which distorts the molecule and lowers its symmetry, converting the triplet to a singlet ground state. [3]
