Name the following:
e.

Verified step by step guidance

Step 1: Identify the functional group in the molecule. The structure contains a carboxylic acid group (-COOH), which is characterized by a carbonyl group (C=O) attached to a hydroxyl group (-OH). This indicates that the compound is a carboxylic acid.

Step 2: Determine the longest continuous carbon chain that includes the carboxylic acid group. The chain consists of six carbons, making the parent name 'hexanoic acid'.

Step 3: Number the carbon chain starting from the carboxylic acid group, as it has the highest priority in nomenclature. The carboxylic acid group is always assigned position 1.

Step 4: Identify and name any substituents attached to the main chain. There is a methyl group (-CH3) attached to the second carbon in the chain.

Step 5: Combine the substituent name with the parent name, ensuring proper placement of the substituent's position number. The final name is '2-methylhexanoic acid'.

Key Concepts

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

Carboxylic Acids

Carboxylic acids are organic compounds characterized by the presence of a carboxyl group (-COOH). This functional group consists of a carbonyl (C=O) and a hydroxyl (O-H) group, making carboxylic acids acidic in nature. They are commonly found in various natural substances and are important in organic synthesis and biochemical processes.

IUPAC Nomenclature

The International Union of Pure and Applied Chemistry (IUPAC) nomenclature provides a systematic method for naming organic compounds. For carboxylic acids, the longest carbon chain containing the carboxyl group is identified, and the suffix '-oic acid' is added to the name of the corresponding alkane. Proper naming also involves numbering the carbon chain to indicate the position of the functional groups.

Functional Groups

Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. In the case of carboxylic acids, the carboxyl group is the functional group that defines their reactivity and properties. Understanding functional groups is essential for predicting the behavior of organic compounds in chemical reactions.
