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

Identify and provide an explanation of the differences between homogeneous and heterogeneous sampling in the context of sampling methods.

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.
