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.
![### 6.6 Draw the Structure of the Product
The image illustrates a reaction mechanism involving a benzene ring with substituents undergoing transformation.
#### Initial Structure:
- **Benzene Ring:** The central feature of the structure, depicted as a six-membered carbon ring with alternating double bonds.
- **Nitrogen (N) Substituent:** Attached to the benzene ring, carrying a positive charge. Double-bonded to two oxygen (O) atoms, each of which has a negative charge.
- **Chlorine (Cl) Substituent:** Attached to the benzene ring, depicted with lone pairs.
- **Hydroxyl (OH) Group:** Another substituent on the benzene ring.
#### Arrows:
- Red curved arrows indicate electron movement, highlighting the flow of electrons during the reaction. These suggest a nucleophilic attack or rearrangement leading to the product.
#### Reaction Arrow:
- A horizontal arrow pointing to the right indicates the direction of the reaction from reactants to product. The specifics of this product are not shown in the image, and the task is to determine the final structure based on the given reactants and electron flow.
This diagram is essential for understanding the transformation in the reaction mechanism and predicting the structure of the product.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc62819af-1f81-4d59-bfb3-1ca1702855ed%2Fa886375c-a0d4-439f-a5e2-dd4e1ff24f4e%2F4qi12t6_processed.png&w=3840&q=75)
