6.1 Sixth Edition Intermolecular Forces

Postby Sarah Bui 2L » Sun Nov 11, 2018 10:56 pm

In this question, why is it that NH2OH has london forces, dipole-dipole, hydrogen bonding, but CBr4 only has London forces listed?

Identify the kinds of intermolecular forces that might arise between molecules of each of the following substances: (a) NH2OH; (b) CBr4;

CBr4 would have a VSEPR shape that is tetrahedral, and since the difference between carbon and bromine electronegativity values are 0.3 (2.8(br)-2.5(c)), the molecule is non-polar. Therefore, the only IMFs that would be present in a non-polar molecule are london dispersion forces.

I think CBr4 only has London forces because it is a non polar molecule. London forces are always present so CBr4 only has London forces.
