Quiz Key, Supplemental Online Material

Remember, chem30b.blogspot.com is the course website. This will contain a record of all emails sent out for this class!

The quiz #3 key is here.

Supplemental Material:

Throughout the semester, I will be providing you with readings, videos, etc. that will supplement the lecture. The textbook is unfortunately not sufficient for providing you with a thorough understanding of the topics we will be covering. A good example of this is the discussion of atomic and molecular orbitals from Thursday's lecture, which fall under the heading of what is called Valence Bond Theory. While it is not critical for you to understand valence bond theory to know how C-C multiple bonds behave in organic compounds, it is incredibly helpful for you to know why organic compounds act the way they do. My pedagogical philosophy is to teach the why as well as the result, because I believe that knowing the reasons behind chemical phenomena will a) make those phenomena easier to remember, b) allow you to develop a chemical intuition for solving problems that are unlike ones you have solved before, and c) give you an deeper understanding of chemistry.

So, you should consider the following supplemental material to be required reading/viewing. Studying the following material is not an optional exercise!

Organic Nomenclature:

There are several webpages to this site, navigate through them using the "Next" and "Previous" Links at the bottom of the page.

The material on this site goes farther than chapter 12 in your textbook, but covers material that we will eventually get to.

Atomic Orbitals, Hybrid Orbitals, and Valence Bond Theory

The following videos are made by Salman Khan, who runs the site khanacademy.org. This website has many videos of a n introductory nature on subjects ranging from chemistry, physics, and biology, to economics and banking. These videos are incredibly helpful for anyone starting study on a new topic.

An introduction to orbitals

More on orbitals and electron configurations

Ionic, covalent and metallic bonding (you can skip the part on metallic bonding since that is decidedly unimportant for our class).

This is a quick introduction to valence bond theory, ending with a description of bonding in ethene, where we ended in lecture on Thursday.

A slightly more in-depth discussion of valence bond theory can be found here.

This file on valence bond theory provides yet another quick view of the topic.
