Butane Formulas and Structures

The video tutorial explains the empirical, molecular, and structural formulas for butane. It begins with the molecular formula C4H10, detailing the number and type of atoms. The structural formula is then discussed, showing the bonding of carbon and hydrogen atoms in butane, an alkane with single bonds. Finally, the empirical formula C2H5 is derived by simplifying the molecular formula. The video concludes with a summary of these concepts.
