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 2:** Give the IUPAC name for each compound.
**Diagram Explanation:**
The image contains six organic structures labeled from a to f. Each structure represents a different organic compound that requires naming according to IUPAC conventions:
a. A hexagon representing a six-membered cyclohexane ring with a single methyl group attached (methylcyclohexane).
b. A pentagon representing a five-membered cyclopentane ring with two methyl groups attached (1,2-dimethylcyclopentane).
c. A hexagon representing a six-membered cyclohexane ring with a single ethyl group attached (ethylcyclohexane).
d. Two hexagons fused together, indicating a bicyclic structure with methyl groups attached (1,2-dimethylbicyclo[1.1.0]butane).
e. A linear chain of six carbon atoms (hexane).
f. A cyclohexane ring with a methyl and ethyl group attached (1-ethyl-2-methylcyclohexane).
Students are asked to determine the correct International Union of Pure and Applied Chemistry (IUPAC) names for each of the compounds based on their structures.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4ddf1583-af9c-4cdb-b832-89f0a6e45ec4%2Fb5c7c049-27f5-48e5-b6fc-bc6a76feb35f%2Furo3ty_processed.jpeg&w=3840&q=75)

Why would e) not be 1-cyclopropylpentane? I was under the impression that since the chain has more carbons that it would take priority as the root.
For f) does it matter which substituent you prioritize for the lower number?
