Textbook Question

Correct the following incorrect names:
e. meta-bromotoluene
f. 6-ethyl-4-iodoaniline

Verified step by step guidance

Step 1: Identify the structure of the compound from the image provided. Look for the longest continuous carbon chain to determine the base name of the compound.

Step 2: Number the carbon atoms in the longest chain starting from the end nearest to the first substituent group. This will help in assigning the correct locants to the substituents.

Step 3: Identify and name all substituents attached to the main carbon chain. Common substituents include alkyl groups like methyl, ethyl, etc., and functional groups like hydroxyl, halogens, etc.

Step 4: Combine the names of the substituents with the base name of the compound. Ensure that substituents are listed in alphabetical order and use the correct locants to indicate their positions on the main chain.

Step 5: Check for any stereochemistry or special naming rules that might apply, such as E/Z or R/S configurations, and include them in the name if necessary. Review the IUPAC naming rules to ensure the name is correct.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

IUPAC Nomenclature

IUPAC nomenclature is a systematic method for naming organic chemical compounds. It provides rules for naming based on the structure of the molecule, including the longest carbon chain, functional groups, and substituents. Understanding these rules is essential for correctly identifying and naming compounds, which is crucial for effective communication in chemistry.

Functional Groups

Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. Common functional groups include hydroxyl (-OH), carboxyl (-COOH), and amino (-NH2) groups. Recognizing functional groups is vital for determining the properties and reactivity of organic compounds, which aids in their correct naming.

Structural Isomers

Structural isomers are compounds that have the same molecular formula but different structural arrangements of atoms. This can lead to different physical and chemical properties. Understanding structural isomerism is important for accurately naming compounds, as different structures can have distinct names even if they contain the same number of atoms of each element.
