What is a heterocyclic aromatic compound?
A heterocyclic compound is an organic compound in which one or more of the carbon atoms in the backbone of the molecule has been replaced by an atom other than carbon. Typical hetero atoms include nitrogen, oxygen, and sulfur.
What are heterocyclic compounds give an example?
The most common heterocycles are those having five- or six-membered rings and containing heteroatoms of nitrogen (N), oxygen (O), or sulfur (S). The best known of the simple heterocyclic compounds are pyridine, pyrrole, furan, and thiophene.
What are the two types of heterocyclic compounds?
Based on structure, we can classify Heterocyclic compounds into five types: Three-Membered Heterocyclic Compounds. Four-Membered Heterocyclic Compounds. Five-Membered Heterocyclic Compounds.
What are heterocyclic compounds and its classification?
A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different elements as members of its ring(s). Heterocyclic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of these heterocycles.
Which is a heterocyclic compound?
Heterocyclic compounds are cyclic compounds with the ring containing carbon and other element, the component being oxygen, nitrogen and sulfur. The simplest of the five membered heterocyclic compounds are pyrrole, furan and thiophene, each of which contains single heteroatoms.
What are Homocyclic and heterocyclic compounds?
Homocyclic Compounds: Homocyclic compounds contain atoms of the same element bonded to each other forming a ring. Heterocyclic Compounds: Heterocyclic compounds contain atoms of at least two different elements bonded to each other forming a ring.
Which is heterocyclic compound?
What are Homocyclic and heterocyclic compounds give examples?
Examples. Homocyclic Compounds: Some examples of homocyclic compounds include benzene, cyclohexane, toluene, cyclohexanol, etc. Heterocyclic Compounds: Some examples of heterocyclic compounds include pyran (contain oxygen), azocine (contain carbon and nitrogen), thiocane (contain carbon and sulfur), etc.
How many classes of heterocyclic compounds are there?
Since 1950, five different classes of three-membered ring compounds with two heteroatoms have been discovered. They are derivatives of the parent ring systems diaziridine (containing N―N), oxaziridine (O―N), thiaziridine (S―N), dioxirane (O―O), and dithiirane (S―S).
What heterocyclic means?
Definition of heterocyclic : relating to, characterized by, or being a ring composed of atoms of more than one kind.
What is an aliphatic compound?
An aliphatic compound is an organic compound containing carbon and hydrogen joined together in straight chains, branched chains, or nonaromatic rings. It is one of two broad classes of hydrocarbons, the other being aromatic compounds.
What is a heterocyclic compound?
Heterocyclic compound. Heterocyclic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of these heterocycles. Examples of heterocyclic compounds include all of the nucleic acids, the majority of drugs, most biomass (cellulose and related materials), and many natural and synthetic dyes.
What is an aliphatic hydrocarbon?
Aliphatic Hydrocarbon Meaning – Aliphatic usually implies an aliphatic compound, meaning an organic compound in which the atoms are bound by single, double, or triple bonds to form nonaromatic structures.
Are aliphatics cyclic or aromatic molecules?
A few aliphatics are cyclic molecules, but their rings are the ones that are not as stable as those of the aromatic compounds. While hydrogen atoms are the most commonly bound ones to the carbon chain, nitrogen, oxygen, chlorine, or sulfur atoms might also be present.
