Alkanes and Their Properties

The video tutorial explains how to name the alkane C3H8 as propane. It covers the structure of alkanes, which have all single bonds, and introduces a formula to identify alkanes based on the number of carbon and hydrogen atoms. The tutorial demonstrates the application of this formula with examples like decane (C10H22) and concludes with a recap of the naming process.
