Based on their composition and structure, list CH₂Cl₂, CH₃CH₂CH₃, and CH₃CH₂OH in order of (c) increasing surface tension

Video transcript

Hey everyone, we're asked to arrange the following compounds in order of decreasing surface tension. Now we've learned that as our inter molecular forces increase, our surface tension will also increase. So let's go ahead and compare our inter molecular forces for each one. We can see that we have an oxygen here, which means that we have hydrogen bonding. And this is going to be one of our strongest inter molecular forces. So this means that this compound will have the largest surface tension due to that hydrogen bonding. Next. We know that the compound with our chlorine will be next. And the reason why is because this compound exhibits dipole dipole interactions and this occurs between two polar covalin compounds. And lastly we have our last compound which is filled with hydrocarbons and because it is filled with hydrocarbons, the only inner molecular force present here is going to be dispersion forces, which is going to be our weakest inner molecular force. So this is going to be our final answer for this question. Now I hope that made sense. And let us know if you have any questions
