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.
![**Identify the Functional Class of Each Molecule**
Use the structures provided to determine the functional class of each molecule (e.g., alcohol, amine, thiol, etc.). Write your answer below each molecular structure.
**Molecular Structures:**
1. The first molecule contains a carbon chain with a sulfur-hydrogen group (–SH) attached.
2. The second molecule has a central carbon atom attached to three hydrogen atoms and one amine group (–NH2).
3. The third molecule consists of a double bond between two carbon atoms (–C=C–).
4. The fourth structure features a carbon double-bonded to an oxygen atom (–C=O) with an additional single-bonded oxygen-hydrogen group (–OH).
5. The fifth molecule includes a carbon double-bonded to an oxygen atom (–C=O) and single-bonded to a sulfur-hydrogen group (–SH).
6. The sixth molecule resembles the fourth structure but features an additional single-bonded oxygen atom connected to another carbon chain (–C=O–O–).
**Provide the Functional Classes Below:**
1. **Functional Class:** Thiol
