The video tutorial explains how to write the structure for 3-ethyl 4-methyl hexane. It begins by identifying the compound as an alkane, characterized by single-bonded carbon atoms. The tutorial then constructs a six-carbon hexane chain and adds a methyl group to the fourth carbon and an ethyl group to the third carbon. The final structure is reviewed, and the molecular formula C9H20 is provided.
