Okay guys I have a question that does not make sense to me.
My teachers, and even the chem and bio textbooks, have often said that polar molecules bond with each other, and non-polar molecules bond with each other.
I do get why polar molecules can form bonds, which is due to the e- arrangement, allowing for uneven spread of e-.
However, why do non-polar molecules bond with each other? Ofcourse the explanation is temporary dipoles, but all molecules exhibit that.
So why would, let's say, CH4 (l) mix with itself better than water? (Not considering molecular size)
Yea it's not polar so it mainly forms LDF w/ H2O, but it only forms LDF with itself too. And if anything, it should form stronger bonds with H2O because H2O at least exhibits polarity, and the C-H bond is not super un-polar, so a CH4-H2O bond would be more dipole-dipole than a CH4-CH4. Unless I am wrong in something I have stated (in which case please correct me).
So guys what's the explanation for this?
