Thiamine or vitamin B1, contains a positively charged five membered nitrogen-sulfur heterocycle ring called a thiazolium ring. Why the thiazolium ring is aromatic is to be explained. Concept introduction: According to Huckel’s rule a planar, cyclic conjugated system will be aromatic if it contains (4n+2)Ï€ electrons. Systems with 4nÏ€ electrons will be antiaromatic. To explain: Why the thiazolium ring in Thiamine or vitamin B1 is aromatic.

Question

5Thiamin, or vitamin B1, contains a positively charged five-memberednitrogen–sulfur heterocycle called a thiazolium ring. Explain why the thiazoliumring is aromatic.

Answer 1

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.
