WebThe chart below shows the boiling points of the following simple primary alcohols with up to 4 carbon atoms: These boiling points are compared with those of the equivalent alkanes (methane to butane) with the same number of carbon atoms. Notice that: The boiling point of an alcohol is always significantly higher than that of the analogous alkane. WebApr 5, 2024 · Hence, option (A) is correct, increasing its melting point. Note: Melting point and boiling point, both the factors depend on the surface area and branching. As the …
Does melting point decrease with branching? [Facts!]
It’s also about surface area. It’s a nice story: branching decreases melting point and boiling point. But it gets more complicated. Look at these three examples of branched hexane derivatives (with hexane for comparison) It looks like as we increase branching, we’re increasing melting point and decreasing boiling … See more The above photo shows what is perhaps one of the worst games of Tetris ever played. In my defence, the point wasn’t so much to play, but to take a photo of the great setup the Tech … See more It’s a nice story: branching decreases melting point and boiling point. But it gets more complicated.
