Classes Of Functional Groups
Organic Chemistry deals mostly with carbon and hydrogens, also called hydrocarbons, but those groups which replace hydrogen and bonds with carbon to give a characteristic nature, unique of their own, to the hydrocarbon they are attached to, are called functional groups. All the compounds belonging to a functional group undergo reactions in a similar pattern and are known to have similar physical and chemical properties.
Characteristics Of Functional Groups
In organic chemistry, we encounter a number of special substituent groups which are attached to the hydrocarbon backbone. These groups impart certain characteristics to the molecule of which it is a part of and thus, become the highlight of that particular molecule.
IUPAC Nomenclature
In Chemistry, IUPAC stands for International Union of Pure and Applied Chemistry which suggested a systematic naming approach for the organic and inorganic compounds, as in the beginning stage of nomenclature one single chemical compound was named in many ways by which lead to confusion. The need for this approach aroused as the number of chemical compounds newly discovered were increasing (approximately 32 million compounds) and the basic concept of nomenclature i.e. the trivial nomenclature and the derived system of nomenclature failed to overcome the challenge. It is an important task to name a chemical compound systematically and unambiguously which reduces lots of confusion about the newly reported compounds.
![**Question:**
What is the correct name of this compound?
**Diagram:**
The structure depicted shows a molecule with four carbon atoms forming a straight chain. Attached to the second carbon atom (when counting from the left) is a bromine (Br) atom, indicated by a wedge to show that it is in a specific stereochemical configuration.
**Answer Choices:**
- R-2-bromopentane
- S-2-bromobutane
- S-2-bromopentane
- R-2-bromobutane
**Explanation of Diagram:**
The chemical structure displayed is a skeletal formula representing:
- A chain of four carbon atoms.
- A bromine atom attached to the second carbon, with a specific stereochemistry indicated by the wedge.
Students are required to name the compound based on its structure, including its stereochemical configuration (R or S) and the number of carbons in the chain (butane or pentane).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F67028db1-3c15-42d7-aa43-8659f6c3f0f2%2F351b8dd1-dee7-4d7c-9d22-84725df2e94f%2Fkidslwb_processed.png&w=3840&q=75)
