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.
![### Understanding Chemical Nomenclature
**Question: What is the name of the following compound?**
To answer questions about chemical compounds, it's important to understand the structure and naming conventions in organic chemistry.
**Diagram Explanation:**
The image above contains a structural diagram for a chemical compound. The compound consists of the following features:
1. **Cyclohexane Ring:** The core structure is a cyclohexane ring, which is a six-membered carbon ring with single bonds.
2. **Substituents:**
- **Isopropyl Group:** An isopropyl group (-CH(CH3)2) is attached to the first carbon of the cyclohexane ring.
- **Butyl Chain:** A butyl group (-C4H9) extends from another carbon on the ring.
**Naming the Compound:**
To name the compound correctly:
1. Identify the main carbon chain or ring. Here, the cyclohexane ring is the main structure.
2. Identify and name the substituents attached to the main ring.
3. Number the carbon atoms in the ring to give the substituents the lowest possible numbers.
Based on standard chemical nomenclature:
- The cyclohexane ring is numbered starting from the carbon with the isopropyl group.
- The isopropyl group is on carbon 1.
- The butyl chain is on carbon 4.
Thus, the correct name for the compound is **1-isopropyl-4-butylcyclohexane**.
By understanding these steps, you can determine the systematic name of various organic compounds.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F9c9849aa-211e-4bc0-b610-ffe665c6b4be%2Fa2a3be4d-f4fa-4128-8c0f-bca8147251f8%2Fcax38c_processed.png&w=3840&q=75)
