In question 6 it asks, what type of intermolecular bonding occurs in gaseous CH4?
a. covalent
b. ionic
c. hydrogen
d. van der Waal's

I chose A but found out that the correct answer is D. van der Waal's. I'm just confused as to why D is the answer and not A.

 

[Wagz]

The molecule itself is non-polar covalent but its intermolecule force is van der waal or london dispersion with other CH4 since there is no ionic or hydrogen bonding

Covalent is a INTRAmolecular force it happens within the molecule
INTERmolecular force is what happens between molecules.
A. Colvalent is an INTRAmolecular force
B.Ionic happens between salts
Hydrogen Bond can only occur between a H and N, H and F or a H and O
D. Is the right choice. Van Der Waal's Forces are the weakest forces and ususully ALWAYS occur.
