Boiling point elevation and freezing point depression

The surface area of the molecule depends on the amount of Van Der Waal’s force acting between the molecules. The force of attraction increases with the increase in surfsce area. Due to strong attractive forces the boiling becomes difficult. If the carbon atoms make a compound using branches then it might … See more Boiling point is that value of temperature at which the vapour pressure of the liquid surface reaches the value of pressure of the surroundings. By increasing the temperature we are … See more The correct interpretation of this question is what is the effect of surface area on the boiling point of the mixture? We all must have known by now the effects of temperature and pressure on the boiling point. When the … See more We have already discussed this in above sections that the boiling point of the compound will increase if the chain has more carbon atoms attached in a linear fashion. It is … See more The relation between boiling point and surface area is already discussed in the above section. The boiling point increases as the surface area of the molecular compound increases. … See more WebNov 14, 2013 · The above extract from my book, mentions clearly that branching makes the molecule more compact and thereby decreases the surface area.

The reaction involves collision between … WebFeb 20, 2016 · When a liquid evaporates in the open, the condensation rate is negligible. Increasing the surface area increases the evaporation rate, but it has little effect on the condensation rate. Hence, water in an open dish evaporates faster than water in a test tube, but the vapour pressure does not change. Answer link

WebWhen he's looking at the -OH bonds for each molecule, he's imagining other molecules of the same chemical in close proximity engaging in hydrogen bonding thus creating stronger attractions between the molecules which affects their boiling points. This is also why he investigates their London dispersion forces which is weaker intermolecular force. http://www.madsci.org/posts/archives/2000-03/953908096.Ph.q.html

WebWhat is the effect of branching of alkane on its boiling point? As branching increases, the surface area of the molecule decreases which results in a small area of contact. As a result, the Van der Waals force also decreases which can be overcome at a …

WebApr 16, 2024 · Increasing the contract surface area between hydrocarbons raises boiling point, so hexane should have a higher boiling point than propane. This doesn't really make sense to me. What is the difference between pulling apart a pair of propane twice, versus one pair of hexane? Why would the total amount of energy needed differ?
