WebMay 21, 2016 · Explanation: Look at the alkane series: methane, ethane, propane, butane, etc. The longer the alkyl chain, the greater the degree of dispersion force between molecules, and thus the greater the boiling point. Of course, as a chemist, as a physical scientist, you should look up the boiling point of the straight chain alkanes. Of course, … WebFor n-alkanes and branched alkanes, the MIR-boiling point relationships are described by a nonlinear regression equation to reflect their similarity in reactivity [MIR = 1.99 - 0.0034(BP) + 1.01 x 10-6 (BP) 2]. Using these equations, reactivity calculations for HCS can be modeled by a hypothetical n-alkane-branched-alkane species and a cycloalkane.

All About Melting Points of the Alkanes - Unacademy

WebBranched alkanes with the same carbon content usually have lower boiling points than unbranched alkanes. Because the van der Waals forces between molecules of unbranched alkanes are stronger, this happens. In the natural world, these forces can be dipole dipole, dipole induced dipole, or induced dipole induced dipole. WebThe main source of these liquid alkane fuels is crude oil, a complex mixture that is separated by fractional distillation. Fractional distillation takes advantage of the different boiling points for components of the mixture. This is a real life example of how boiling point is a function of intermolecular interactions.
