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?
CH4 ≥ NH3 because CH4 is tetrahedral but NH3 is pyramidal.
CH4 < NH3 because δ− on C in the CH bond is greater than δ− on N in the NH bond.
CH4 < NH3 because the NH bond is more polar than the CH bond.
CH4 ≥ NH3 because CH4 has H bonding but NH3 has dispersion forces.
