Represent each of the following condensed structural formulas using a line-angle drawing.
(d) CH₃CH₂CH₂CCH₂OH

Guida verificata passo dopo passo

Step 1: Identify the main chain of the molecule. The condensed formula CH3CH2CH2CCH2OH indicates a five-carbon chain with a hydroxyl (-OH) group attached to one of the carbons.

Step 2: Recognize the functional groups and special bonds. The molecule contains a hydroxyl (-OH) group and a triple bond between the fourth and fifth carbons (C≡C).

Step 3: Begin drawing the line-angle structure. Represent each carbon atom as a vertex and each bond as a line. Start with the first three carbons (CH3CH2CH2) as a straight chain.

Step 4: Add the triple bond between the fourth and fifth carbons. Use three parallel lines to represent the triple bond in the line-angle drawing.

Step 5: Attach the hydroxyl (-OH) group to the fifth carbon. Represent the oxygen atom as a line extending from the vertex of the fifth carbon, and include the hydrogen atom bonded to the oxygen.

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

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 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 hydroxyl group (–OH) is a functional group that indicates the presence of an alcohol, influencing the molecule's reactivity and properties. Recognizing functional groups is essential for understanding the behavior of organic compounds.
