Whether the cycloheptatrienyl radical is aromatic or antiaromatic is to be identified Concept introduction: An aromatic molecule must obey Hückel’s rule of (4n+2)π electrons where n is an integer. Aromatic molecules are cyclic and planar and have cyclic conjugation. Antiaromatic molecules are cyclic and planar and have cyclic conjugation like aromatic molecules, but they have (4n)π electrons instead (4n+2)π electrons. A carbon radical contributes single π electron.

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.

7 The pentadienyl radical, H2C“CH¬CH“CH¬CH2 ) Draw the MOs of the pentadienyl system in order of increasing energy

Following the instructions for drawing the energy levels of the molecular orbitals for the compounds shown in Figure 8.17, draw the energy levels of the molecular orbitals for the cycloheptatrienyl cation, the cycloheptatrienyl anion, and the cyclopropenyl cation. For each compound, show the distribution of the p electrons. Which of the compounds are aromatic?

Why isn't this compound aromatic? Doesn't it fit the 4n+2 rule where there is 6 pi electrons? Or is it not planar, which is why it is not aromatic?
