Free O-Chem Lectures for MCAT, DAT, PCAT, and GRE prep -- Video 2: physical properties of matter.mov

The purpose of this video is to help second-year organic chemistry students review the concepts and questions that most frequently appear on standardized entrance exams, like the MCAT, DAT, PCAT, and GRE. In this video I'll teach you how to arrange molecules in order of highest to lowest boiling point, highest to lowest acidity, and highest to lowest solubility in a given solvent. This requires a review of intermolecular forces: London (Van der Waals) forces, dipole-dipole, and hydrogen-bonding. I'll also teach you how to identify a compound's empirical formula and its "degrees of unsaturation," how to predict which reaction in a series will be the most exothermic or endothermic (enthalpy), and how to compare two isomers and identify their isomeric relationship. --Dr. Mike Christiansen from Utah State University.

you are truly amazing 

[Mike Christiansen]

Thanks.

WOOOW

I reallly appreciate your videos! They really help me review my orgo because it has been a while since I had an orgo class! THANK YOU for posting them :)

I hope you get a chance to post the answers to lecture questions, even if it is on a piece of paper listing the answer choice letter.

[Mike Christiansen]

Thanks for the praise. I really appreciate knowing that my videos are helping people learn chemistry. I promise that I will post answers to my questions, though I won't have time to do so until probably this summer, due to my extraordinarily demanding schedule. Best of luck in orgo!

Hi. I appreciate your lectures! They very helpful! But I'm wondering where do you give the answers to the lecture question?

[Mike Christiansen]

Awesome. I'm so glad to hear that. Thanks for the praise. Good luck with everything.

i love you bro...this lectures really help...specially since i have been out of school for so long

[Mike Christiansen]

I am so sorry, but I haven't yet made any video lectures containing the answers to these questions. These videos were originally developed for my face-to-face class, to whom I gave the answers during class. As soon as my schedule allows, I'll post a video containing the answers, I promise. I'm sorry that this hasn't occurred yet. Thanks for watching!

These videos have been extremely helpful! Thank you! I was wondering where you posted the answers to the questions? Like maybe a blog or something? I really appreciate these lectures, you make it fun and entertaining to review.

[Mike Christiansen]

My apologies. I haven't yet given the answers to these questions. I originally created these lectures for my students at the university, and I gave them the answers in class. I only afterward posted them to YouTube. I promise that I will, at a later date, provide my YouTube subscribers with the answers, when my schedule allows. Sorry, once again, but I PROMISE I will post them eventually. Thanks for watching!
