WebJul 7, 2024 · What effect does branching of alkane have on boiling point? As branches increases, the surface area of molecule decreases resulting in a small area of contact. As a result, the Van der Waals force also decreases which can overcome at a relatively lower temperature. Hence, the boiling point of an alkane chain decreases with an increase in … Web1. number of carbons (increase in number of carbons, and hence molecular weight, increases BP) 2. Like you said, surface area. (increase in SA results increase in BP) 3. The strength of IMF. So I believe, that because nonane has more number of carbons AND more surface area, that's TWO factors that makes it have higher BP.

The influence of each of these attractive forces will ... WebSep 7, 2024 · Why pressure affects boiling point? Pressure affects the boiling point of a liquid because it causes the pressure to increase within the liquid. The higher the pressure, the higher the temperature at which water will start to boil. This is because when water reaches its boiling point, the vapor pressure of water is equal to atmospheric pressure.
