Butane, the fuel used in disposable lighters, has the formula C4H10. The carbon atoms are connected in the sequence C-C-C-C, and each carbon has four covalent bonds. Draw the structural formula of butane.

Welcome back everyone. Propane yeast and Barbecue Grills has a formula C three H eight, the carbon atoms are arranged as follows CCC draw propane structural formula given that each carbon forms four covalent bonds. As the problem suggests, we want to have AC CC chain. So what we're going to do is just to draw we carbon atoms bonded to each other via single bonds. Each carbon must have more bonds, right? And we have eight hydrogens available. So what we're going to do is add three additional bonds for the first carbon, two for the metal carbon because it has two bonds and three more for the which gives us 12345678 additional bonds. And these would correspond to the carbon hydrogen bonds, right? Because we have eight hydrogens available. So we simply want to draw eight hydrogens at the end of each bond. And if we look at the structure, we indeed have three carbons and eight hydrogens. This gives us the structural formula for propane. That's our final answer. And thank you for watching.
