Textbook Question

Indicate whether each of the following pairs represent structural isomers or the same molecule:

b. <IMAGE>

Verified step by step guidance

Identify the molecular formula of each compound in the pair. Structural isomers have the same molecular formula but different structures.

Examine the connectivity of atoms in each compound. Look for differences in the arrangement of atoms or the presence of different functional groups.

Check for any differences in the branching of carbon chains or the position of functional groups, which can indicate structural isomerism.

Consider any possible stereochemistry, such as cis/trans isomerism, which can also result in different structures.

Conclude whether the compounds have the same connectivity and structure (same molecule) or different connectivity (structural isomers).

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Structural Isomers

Structural isomers are compounds that have the same molecular formula but differ in the arrangement of atoms within the molecule. This can include variations in the connectivity of atoms or the presence of different functional groups. Understanding structural isomers is crucial for distinguishing between molecules that may have similar properties but different chemical behaviors.

Molecular Formula

The molecular formula represents the number and types of atoms in a molecule, providing a shorthand way to describe its composition. For example, C6H12O6 indicates a molecule with six carbon atoms, twelve hydrogen atoms, and six oxygen atoms. Recognizing that different structural isomers can share the same molecular formula is essential for identifying whether two compounds are isomers or identical.

Functional Groups

Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. They play a significant role in determining the properties and reactivity of organic compounds. Identifying functional groups can help differentiate between structural isomers, as variations in these groups can lead to different chemical behaviors despite having the same molecular formula.
