What Are Structural Isomers

The video tutorial covers the concept of alkanes and structural isomers, starting with the first four alkanes: methane, ethane, propane, and butane. It explains how structural isomers have the same molecular formula but different structural arrangements, using butane as an example. The tutorial also discusses the history of lead-free petrol and the role of octane isomers in improving engine performance. Finally, it explores the structural isomers of hexane, providing their formal names and emphasizing the importance of the longest carbon chain in naming isomers.

Explain the role of lead tetraethyl in petrol and its impact on the environment.

Identify the four isomers of hexane and provide their formal names.

What are the two types of structural isomers based on pentane and butane?
