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. WebSep 14, 2024 · As alcohol evaporates at a much faster rate compared with water due to its lower boiling temperature (82 compared to 100 degrees C), it is able to carry away more heat from the skin.
