Water: Chemistry and Properties, Part 1

The video covers:
1) How polar covalent bonds develop within a water molecule because of unequal electron sharing
2) How these bonds make water a polar molecule.
3) How water's polarity makes it a "sticky" molecule, resulting in hydrogen bonds that cause molecular cohesion among water molecules.

This video covers content associated with AP Bio Topic 1.1, "Structure of Water and Hydrogen Bonding."

You explained better than the textbook AND the online articles we were told to read. I did not understand polar concept till this

I am using all of your biochemistry videos to submit my waitlist form into ap bio for my school. They are helping me self study so much :)

Thank you so much, this was so helpful and really made it more clear of what I'm learning in Biology, amazing video and great job!❤️

Great videos! Really helpful. Amazing teacher.

I had to go over it a dozen times in some places but to me it was fun. IT was easy if you stick with it.Thank you very much, great lectures.

Why weren't you teaching high school chemistry 40 years ago? Oh that's right you were my age. LOL wow, I don't know what it is about you but I absorb it. You made something so elusive understandable. Thank you for taking the time and uploading these short series. Kudos for making the connection

Thank you so much! I really want to learn biology but did not have any basic knowledge on chemistry (cuz i forgot all about it lol)

I got a question. You stated the following: "because there are so many more positive charges in the oxygen nucleus than in either of the two hydrogen nuclei, the way that the negative electrons are shared, isn't equal." And then you went on to explain that this causes polarity. I understand all that. However, what confuses me is that when you compare H2O to CH4, is that it seems that the electrons still aren't shared equally. Although they are spatially equal in CH4, drawn like there are 2 shared electrons in every corner of the outer orbitals, oxygen has a total of 8 electrons in its outer orbital and hydrogen only 2 (or 4 for both hydrogen atoms). So doesn't this mean that the electrons are still unequally shared in CH4 as well?

Great video Mr. W!! You are such a great teacher. :D
