Ethane Composition and Properties

The video tutorial explains how to write the formula for ethane, a hydrocarbon with two carbons and six hydrogens. It covers the Lewis structure, showing single bonds between carbon and hydrogen atoms, and discusses the tetrahedral molecular geometry. The tutorial also demonstrates how to derive the molecular formula for ethane using the alkane formula CnH2n+2, resulting in C2H6.
