Question

Determine which molecule in each of the pairs below has the stronger intermolecular forces.

H₂O or SO3:
NH3 or CH4:
NO or CH3OH:
HF or CCl4
CH3CH3 or CH₂CH₂

Answer 1

CH3OH vs. CH4 CH3OH will have stronger intermolecular forces because it is a polar molecule. There will be forces associated with dipole-dipole and hydrogen bonding due to the OH group.

Step-by-step explanation:

First of all, the question would be, “Which one has weaker intermolecular force- H2O or CH3OH?” As for the answer, it is CH3OH. The hydrogen bonding in CH3OH can only take place between hydrogen attached to oxygen directly.
