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 8: IUPAC Nomenclature and Stereochemistry**
**Task:**
Using IUPAC nomenclature and syntax, name the compound shown below. Include in the compound’s name the Z or E configuration.
**Graph/Diagram Explanation:**
The diagram shows a hydrocarbon chain with eight carbon atoms. The carbons are numbered from 1 to 8 along the longest chain:
- There is a double bond between carbon 4 and carbon 5.
- Methyl groups (CH₃) are attached to carbon 3 and carbon 4.
Notes handwritten next to the structure suggest determining whether the double bond has an E or Z configuration.
**How to Determine E/Z Configuration:**
The configuration (E or Z) of the double bond is based on the priority of the substituents attached to the carbons of the double bond, according to Cahn-Ingold-Prelog priority rules.
1. Look at the groups attached to each carbon of the double bond.
2. Assign priority based on atomic number: higher atomic number = higher priority.
3. Determine the relative positions of the higher priority groups:
- If the higher priority groups are on the same side, the configuration is Z (from German *zusammen* meaning "together").
- If the higher priority groups are on opposite sides, the configuration is E (from German *entgegen* meaning "opposite").
Please proceed to assign the correct name using these rules.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe0bc4f8d-d492-4b99-935f-91b67ee2ab0e%2F79e8effa-e461-46ed-9c63-349f7c7ebf11%2F2lqbwvq.jpeg&w=3840&q=75)
