Highest and lowest boiling point
WebOctane will have a higher boiling point than 2,2,3,3‑tetramethylbutane, because it branches less than 2,2,3,3‑tetramethylbutane, and therefore has a larger “surface area” and more van der Waals forces. Note: The actual boiling points are nonane, 150.8°C octane, 125.7°C 2,2,3,3‑tetramethylbutane, 106.5°C Contributors and Attributions Web3 de fev. de 2024 · According to Table \(\PageIndex{1}\), the molal boiling point elevation constant for water is 0.51°C/m. Thus a 1.00 m aqueous solution of a nonvolatile molecular solute such as glucose or sucrose will have an increase in boiling point of 0.51°C, to give a boiling point of 100.51°C at 1.00 atm.

For example, the boiling and melting points of iso-butane are -12 ° C and -160 ° C, respectively, compared to 0 ° C and -138 ° C for n-butane. The more branching there is, the lower the boiling and melting points are.
