Textbook Question
Give common names for the following compounds.
(g) 
Verified step by step guidance1
Identify the functional groups present in the compound. Common names often depend on the functional groups, such as alcohols, ketones, or carboxylic acids.
Determine the longest carbon chain in the compound. The common name may be based on the number of carbon atoms in this chain.
Look for any substituents attached to the main carbon chain. These can include alkyl groups, halogens, or other functional groups, which may influence the common name.
Consider any historical or traditional naming conventions that might apply to the compound. Some compounds have common names that are widely accepted and used in practice.
Combine the information from the previous steps to construct the common name, ensuring that it reflects the structure and functional groups of the compound.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Common Nomenclature in Organic Chemistry
Common nomenclature refers to the traditional names given to organic compounds, often based on their structure or functional groups, rather than following systematic IUPAC rules. Understanding common names helps in recognizing and communicating about compounds that may not be easily identified by their IUPAC names.

Functional Groups
Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. Identifying functional groups is crucial for determining the common names of compounds, as they often dictate the naming conventions used in organic chemistry.

Structural Representation of Compounds
Structural representation involves depicting the arrangement of atoms within a molecule, which can be shown through various formats such as Lewis structures, condensed formulas, or skeletal structures. Analyzing the structure of a compound is essential for deriving its common name, as it provides insight into the compound's functional groups and overall characteristics.
