1. The problem statement, all variables and given/known data What type of intermolecular bonding occurs in gaseous CH4? (A) covalent (B) ionic (C) hydrogen (D) van der Waals 2. Relevant equations 3. The attempt at a solution Here is what I did: ruled out B (not ionic) and chose A. The correct answer is D. Is C wrong because hydrogen bonding only happens between polar molecules? Why is D correct over A? Is it because covalent = intramolecular, not intermolecular? Thanks in advance.
