What are structural isomers and can you provide examples?
Understand the Problem
The question discusses structural isomers in organic chemistry, highlighting that isomers have the same molecular formula but different structural forms. It also provides examples like pentane and mentions isomers for ethene and propene, focusing on their characteristics.
Answer
Same formula, different structure: e.g., butane (C4H10).
Structural isomers are molecules with the same molecular formula but different structural arrangement of atoms. For example, C4H10 (butane) has two isomers: butane and isobutane.
Answer for screen readers
Structural isomers are molecules with the same molecular formula but different structural arrangement of atoms. For example, C4H10 (butane) has two isomers: butane and isobutane.
More Information
Structural isomers differ in the connectivity of their atoms which results in diverse physical and chemical properties despite having the same number of each type of atom.
Tips
A common mistake is confusing structural isomers with stereoisomers, which have the same connectivity but differ in spatial arrangement.
