Question

This is the problem with the answer . However, I do not understand the math/theory behind this. Can someone break it down? Thanks

ESSAY. W rite your answer in the space provided or on a separate sheet of paper. 68) Which intermolecular for ce is primarily responsible for the interactions among alkane molecules? 名 Ea F5 9 4 5 6

Answer 1

Alkanes --> those are build up by Carbon and Hydrogen bonds

They will not form dipole, since they have similar electronegativities

They share equally their electrons, therefore, the only possible force is "dispersion" forces, also known as london dispersion forces or van der waal interactions.

This is mainly due to hte proton/electron distributino in each atom.

Note that this type of interactionis pretty low compared to dipole interactions, therefore, expect low melting/boiling points
