Understanding 2-Methylpropane Structure

The video tutorial explains how to write the structure for 2-methylpropane, starting with the basic structure of propane, an alkane with three carbons. It describes the process of replacing a hydrogen atom with a methyl group (CH3) to form 2-methylpropane. The video also discusses the different names for 2-methylpropane, including isobutane, and demonstrates various ways to write its structure. The tutorial concludes with a brief thank you from Dr. B.
