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.

In most cases, increased pressure increases the melting point for a material. This means that under high-pressure conditions, you would need to apply more heat to cause a material to melt. Ice is a rare exception to this rule. When you increase pressure on ice, it lowers the melting point temperature. ezus lyon villeurbanneWebApr 1, 2024 · DOI: 10.1016/j.ceja.2024.100489 Corpus ID: 257934750; COSMO Prediction of Siloxane Compounds Absorption on Type 3 and Type 5 Deep Eutectic Solvents @article{Quaid2024COSMOPO, title={COSMO Prediction of Siloxane Compounds Absorption on Type 3 and Type 5 Deep Eutectic Solvents}, author={Thomas Quaid and … himalayanriderp-Toluenesulfonic acid (PTSA or pTsOH) or tosylic acid (TsOH) is an organic compound with the formula CH3C6H4SO3H.
