Question
Hi Dr. Henry Boyter,
I hope I'm finding you in the best of health.
I have a big test called a regent next week in Chemistry.Therefore I don't have a teacher to ask before then.So I hope you can help me.
This is a question that I found in my book with an answer key and don't understand it.Here's the question:
Molecules in a sample of NH3(liquid) are held closely together by intermolecular forces
(1) existing between ions
(2) existing between electrons
(3) caused by different numbers of neutrons
(4) caused by unequal charge distribution
I understand why the answer is 4 because NH3 is polar,but what's wrong with number 2. Isn't covalent bonding between electrons?Thanks for your help.
Covalent bonding is within molecules (intra), not between them (inter). Also, it is the combination of protons and electrons in covalent, not just the electrons (although that is how we describe it). Just electrons would repel, not attract. If the protons didn't matter, then all electrons, no matter the atom, would give the same bonding.
