Aromatic Compounds

The 4n+2 rule, also known as the Hückel’s rule, is the required number of delocalized electrons in a cyclic, planar, a fully conjugated molecule to make it aromatic. For example, let’s see how the 4n + 2 rule is used … Read more

In the previous few posts, we talked about the stability of aromatic compounds and the rules for determining whether a compound is aromatic or not. Aside from experimental data, the stability of aromatic compounds is also confirmed by sophisticated math … Read more

In the previous post, we talked about the lack of reactivity of benzene towards bromination and the Kekulé structure that was suggested to explain these unique features. In short, Kekulé suggested that benzene is an equilibrium mixture of two compounds … Read more

We talked about aromatic and antiaromatic compounds which are recognized based on the Hückel’s rule. In short, the only way aromatic and antiaromatic compounds differ is the number of electrons they have in the conjugated system. All the other criteria … Read more

We have seen that aromatic compounds are cyclic, planar and have a fully conjugated system of orbitals which gives them a special stability. There is, however, one more criterion that compounds must match in order to be aromatic. Not all … Read more

We have seen many different addition reactions of alkenes and conjugated systems. One of them was the reaction of alkenes with bromine. Bromine is a red liquid and it is an indicator for the presence of alkenes since the double … Read more
