Textbook Question
Represent each of the following condensed structural formulas using a line-angle drawing.
(c) CH3CHOHCH2CHBrCH3
Verified step by step guidance1
Step 1: Understand the condensed structural formula CH3CHOHCH2CHBrCH3. This represents a molecule with a chain of five carbon atoms (pentane backbone) and specific substituents attached to the chain.
Step 2: Identify the substituents and their positions. The molecule contains a hydroxyl group (-OH) attached to the second carbon and a bromine atom (Br) attached to the fourth carbon.
Step 3: Draw the main carbon chain as a zigzag line to represent the five carbon atoms in the pentane backbone. Each vertex represents a carbon atom, and the ends of the zigzag represent terminal carbons.
Step 4: Add the substituents to the appropriate carbons. Attach the hydroxyl group (-OH) to the second carbon and the bromine atom (Br) to the fourth carbon. Ensure the correct placement of these groups relative to the main chain.
Step 5: Verify the structure by counting the number of bonds around each carbon atom (four bonds per carbon) and ensuring that all substituents are correctly placed. This completes the line-angle drawing for CH3CHOHCH2CHBrCH3.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Condensed Structural Formulas
Condensed structural formulas provide a simplified representation of a molecule, showing the arrangement of atoms and their connectivity without depicting all the bonds explicitly. In these formulas, groups of atoms are often grouped together, such as CH3 for a methyl group, which helps in visualizing the molecular structure more efficiently.

Line-Angle Drawings
Line-angle drawings, also known as skeletal structures, are a shorthand way of representing organic molecules. In these drawings, vertices represent carbon atoms, and lines represent bonds. Hydrogen atoms attached to carbons are usually omitted for simplicity, making it easier to visualize larger organic structures quickly.

Functional Groups
Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. In the given formula, the presence of the hydroxyl group (–OH) indicates that the compound is an alcohol, while the bromine atom (Br) suggests the presence of a halogen, which can influence the reactivity and properties of the molecule.
