The electronegativity values of carbon, hydrogen, and nitrogen are compared in the table. Comparison of Electronegativity
Element Electronegativity
Carbon 2.5
Hydrogen 2.1
Nitrogen 3.0

Which of the following statements is true about the strength of the intermolecular forces in CH4 and NH3?
A. CH4 ≥ NH3 because CH4 is tetrahedral but NH3 is pyramidal.
B. CH4 < NH3 because δ− on C in the CH bond is greater than δ− on N in the NH bond.
C. CH4 < NH3 because the NH bond is more polar than the CH bond.
D. CH4 ≥ NH3 because CH4 has H bonding but NH3 has dispersion forces.

*At first I thought that it was B, but that was definitely wrong. I want to know how to do these because this is the second one I have gotten wrong. I am getting frustrated, because I like to learn from my mistakes. So, if anyone knows how to do it, please explain! Thanks!*
