I am confused about this question; viscosity is the resistance to flow, right? Then, which molecule would it be because #1 = is Dibromomethane, which I searched up, and it said it's very dense and denser than water, so it would have low viscosity. Then #2, I don't know. , I searched it up and it said Ethylene Glycol, then #3 is Phelethanol, I think, and #4, methyl chloride, which is a refrigerant I'm pretty sure, and #5,dimel ether  I also didn't know about this one.

I was generally confused because I thought all of these have low viscosities, but when I submitted the quiz it said #2, Ethylene Glycol has the highest viscosity,  could you explain why it's Ethylene Glycol? Does this have to do with the IMF (inter-molecular forces of attraction)? Sorry if this doesn't make sense.

First we have not done this topic yet.
Second you are right that it is related to IMFs.And more stronger IMFs ,more tightly  molecules are packed and more slow is the motion.This means less viscosity.Ethylene glycol is more viscous because of more hydrogen bonding.

ohh, that makes sense now, thank you!
