Draw the condensed structural formula, or line-angle formula if cyclic, for each of the following:
c. 1-propanethiol

Verified step by step guidance

1. Identify the parent chain: The name '1-propanethiol' indicates that the parent chain is propane, which consists of three carbon atoms connected in a straight chain.
2. Identify the functional group: The suffix '-thiol' indicates the presence of a thiol group (-SH) attached to the carbon chain.
3. Determine the position of the thiol group: The '1-' prefix indicates that the thiol group is attached to the first carbon atom in the chain.
4. Draw the condensed structural formula: Start with the three-carbon chain (CH3-CH2-CH2-) and attach the thiol group (-SH) to the first carbon atom, resulting in CH3-CH2-CH2-SH.
5. Verify the structure: Ensure that the structure represents 1-propanethiol by checking that the thiol group is on the first carbon and that the carbon chain is correctly represented.

Key Concepts

Condensed Structural Formula

A condensed structural formula is a way of representing a chemical compound that shows the arrangement of atoms and the connectivity between them without depicting all the bonds explicitly. In this format, groups of atoms are often grouped together to simplify the representation, making it easier to visualize the molecular structure. For example, 1-propanethiol can be represented as CH3CH2CH2SH, indicating the presence of a thiol group (-SH) attached to a three-carbon chain.

Line-Angle Formula

The line-angle formula, also known as the skeletal formula, is a shorthand representation of organic molecules where vertices represent carbon atoms and lines represent bonds. This method is particularly useful for cyclic compounds and larger molecules, as it simplifies the drawing by omitting hydrogen atoms attached to carbons. For 1-propanethiol, the line-angle formula would depict a straight chain of three carbon atoms with a terminal thiol group, emphasizing the carbon backbone.

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 1-propanethiol, the functional group is the thiol group (-SH), which imparts unique properties such as odor and reactivity. Understanding functional groups is essential for predicting the behavior of organic compounds and their interactions in chemical reactions.
