Alright, guys, let's take a look at that example that was left for us to do so. Here, it says determine the formula and name of Ah, hydrocarbon that contains Onley, single bonds and eight carbons. So we know it has only single bonds. So it's an Al cane, which means the end of the name of the pain. Eight carbons. We're gonna say the formula B C N h two n plus two. So we're gonna say here that this would be C eight h two times eight plus two So that b c h h 18. So that would be the molecular formula C eight h 18. And then we would say here that if you have a carbons, your prefixes oct And since it's now came the ending his aim So it be octane. This would be the general generic name of this eight carbon al cane chain. Now here we can say there is a direct relationship between Al Canes. Wait and it's measured. Um, it's measured boiling point. We're gonna say generally the greater the molecular weight of it all cane, the higher its boiling point will be. Remember this deals with inter molecular forces we talk about London dispersion forces. These are all hydrocarbons are all non polar. If you're non poll, your inter molecular force is London dispersion and one of the big factors that increases London dispersion Strength is mass. So if you take a look, you're gonna notice that the lighter, high hydrocarbons, the light around canes up to four. They exist as gasses, meaning that they're incredibly easy to vaporize here. As we keep going down, they're gonna transition from liquids and volatile just means that reacts very easily. Heating it up slightly causes immediate change. So here we're going from liquids toe liquid with very high boiling point. Why? Because the masses increasing as we have more and more carbons until we finally get to a point where we have over 50 carbons and then these falcons finally exists as solids at room temperature. They'll exist mainly as petroleum jelly and waxes. Okay, so petroleum jelly and waxes air just hydrocarbons that have been solidified because they have so many carbons. The weights are large, giving them a stronger inter molecular force London dispersion, which gives it a higher boiling point. So just remember, the greater the mass the greater. The boiling point will be an organic when you get to what you're going to greater detail about other factors that could influence the London dispersion forces before right now, just focus on the Mass.
