Is a heterocyclic amine with two nitrogen atoms in a six member ring?

Pyrimidine is a heterocyclic amine that contains two nitrogen atoms in an unsaturated six-membered ring. An example of a molecule that contains pyrimidine is thiamine, which is also known as vitamin B1.

What is a six-membered ring called?

heterocyclic compound – Six-membered rings with one heteroatom.

Which of the following six-membered ring is most resonance?

Explanation: Thiophene is most resonance stabilized five membered rings among above compounds. As thiophene has Sulphur and least electronegativity ring than nitrogen and oxygen in pyrrole and furan respectively.

Can a six membered ring contain an oxygen atom?

An uncharged aromatic (completely conjugated) six-membered ring containing an oxygen or sulfur atom is possible only if the ring contains a carbonyl group (i.e., a ring carbon atom linked by a double bond to an oxygen atom not in the ring), as in the pyrones.

Which is heterocyclic amine has a 5 membered ring?

Nicotine is a molecule containing a pyrrolidine ring attached to a ring of pyridine (other heterocyclic amine). Nicotine belongs to a group of compounds known as alkaloids, which are naturally occurring organic compounds with nitrogen in them. Pyrrole is another compound made up of molecules with a five-membered…
