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.

Students need to utilize their knowledge of IUPAC naming conventions to determine the correct name for the given compound. They should identify the longest carbon chain, analyze the substituents, and apply the appropriate prefixes and numberings to create the systematic IUPAC name. The given buttons are to be used to input the correct nomenclature of the compound.
Explore more about **IUPAC Naming** to enhance your understanding:
- **(E) and (Z) designation:** Helps describe the geometry of double bonds based on the Cahn-Ingold-Prelog priority rules.
- **Numbering Substituents:** Learn how locants (numbers) and prefixes (e.g., iso-, sec-, tert-) are used to indicate substituent positions and types respectively.
- **Longest Chain Selection:** Recognize the longest continuous carbon chain to determine the base name (e.g., hex for a six-carbon chain).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F55a44e3d-6d6a-4ecd-9343-ab7bc7f808c7%2F36c1e2ea-4e79-4fb4-8039-54b7a7f29108%2Fcxdrgh_processed.jpeg&w=3840&q=75)
