Convert the following condensed structures into skeletal structures:
a. CH₃CH₂CH₂CH₂CH₂CH₂OH

Condensed structures are a way of representing organic molecules where the connectivity of atoms is shown without explicitly drawing all the bonds. In these structures, groups of atoms are often grouped together, such as CH3 for a methyl group or CH2 for a methylene group, making it easier to visualize larger molecules without clutter.

Skeletal structures, also known as line-angle structures, are a simplified way of drawing organic molecules. In these diagrams, carbon atoms are represented by the ends and intersections of lines, while hydrogen atoms attached to carbons are usually omitted for clarity. This method emphasizes the overall shape and connectivity of the molecule, making it easier to identify functional groups and molecular frameworks.

Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. In the given structure, the hydroxyl group (-OH) is a functional group that indicates the molecule is an alcohol. Recognizing functional groups is essential for understanding the reactivity and properties of organic compounds.
