WebExample 3.5.1: Boiling Points of Alkanes. For example, the boiling points of the three isomers of C 5 H 12 are: pentane: 309.2 K. 2-methylbutane: 301.0 K. 2,2-dimethylpropane: 282.6 K. The slightly higher boiling points for the cycloalkanes are presumably because the molecules can get closer together because the ring structure makes them tidier ... WebFeb 2, 2024 · However, the geometry is manifestly different, and this geometric isomerism gives rise to different physical and chemical properties. For example, "cis-2-butene" has a boiling point of 3.7 ""^@C; on the other hand, "trans-2 …
