Shown here are cartoons of two different polymers. Which one would have the higher melting point?

Hi everyone for this problem. It reads consider the drawings below, representing two polymers identify which is expected to have a lower boiling point. Okay, so let's take a look at both and see what we see here. So, for our first drawing, we're going to describe it as linear. Okay, when it's linear, that means there is more order. And when we're thinking about order and boiling point, we're thinking about inter molecular forces. Okay, so with it being linear and having more order, we'll say that it has stronger inter molecular forces. Okay, However, for our second polymer, we can describe this one as branched and because it's branch, it's going to have less order than the linear polymer. Okay, with less order, it has weaker into molecular forces. Alright, so in terms of inter molecular forces we can determine the boiling point. Okay, so we can do that by saying the higher the inter molecular force, the higher the boiling point. Because the inter molecular forces are stronger, it's going to need a higher boiling point in order to break those inter molecular forces. Okay, so it has a direct relationship. And so the question asks us which one has the lower boiling point. So the one with the lower boiling point is going to be the one with the weaker into molecular forces. Okay, so that makes answer choice to or image to our correct answer. Okay, so, drawing number two is expected to have the lower boiling point because it has the weaker inter molecular forces. Okay, so that's it for this problem. I hope this was helpful
