Study Aids: Worksheets and Handouts

I have posted quite a few worksheets/handouts listed by topic on the course website. These will be useful for studying for Tuesday's exam. Note that some of the topics listed in this folder are topics we have not covered yet. Please use your own discretion in deciding which handouts to look at.

The worksheets and handouts can be found here.

Announcements Sunday 3/21/2010

Just so you know what to study for the quiz, you will only be responsible for what was covered in lecture. There are quite a few carboxylic acids which you should memorize in the chapter, but not for Tuesday. Also, I will cover more of chapter 17 on Tuesday than is covered in the lecture notes.

Remember to prepare for experiment 11 for Tuesday.

Also, if you want to attend my Monday office hours at 7pm, please email me today.

Lastly, we will be meeting in A204, adjacent to our usual classroom, on Thursday, March 25.

Exam 1

Just a reminder, exam 1 for chem 30b is on Tuesday at 6pm. As I said in class, the exam is meant to be short, but you will have three hours in which to complete it. The exam will potentially cover:


Everything mentioned in lecture so far unless I have explicitly said that you were not responsible for a piece of information
Ch. 12-14 (through the end of section 14.4, not the entirety of chapter 14)
All of the nomenclature in chapters 12-17, as delineated in a previous email.
All supplemental readings unless it was stated that those readings were not required.

Hybridization and Bonding Lecture

If hybridization and bonding are still giving you trouble, you might want to take a look at this video of a general chemistry lecture on the topic at MIT.

Nomenclature Reading

In the 6th Ed. of your textbook, if you by chance have yet to locate the table of contents, you will find nomenclature that will be covered on the first exam in the following sections:

Functional Group: Section of the book
Alcohols: 14.3
Ethers: 14.8
Halides: 14.10
Amines: 15.1
Aldehydes and Ketones: 16.2
Carboxylic Acids: 17.1

You will not be responsible for nomenclature for any of the above functional groups that is more complicated than what I have thus far covered in class. Some examples in these later chapters are more complicated than what you have seen in lecture.

Bonding and Hybridization

If you are having trouble understanding bonding and hybridization, you might find this page form Ohio State at Boise to be helpful.

Carbocations: REQUIRED READING

This site gives a somewhat more advanced take on reactions with alkenes, and describes carbocations. The section on carbocation rearrangements is beyond the scope of this course. If this reading is too much for you, then the next two should be a bit more accessible:

This site gives a good and concise description of the stability of carbocations.

And this is a brief description of Markovnikov's rule

Asides from the Tuesday 2/16 lecture

Note that none of the following is required reading.

After a tiny bit a research, I am still led to believe that trans double bond are more common in nature simply because they are going to be more stable since they involve less of the unfavorable steric interactions I have been talking about in lecture (this unfavorable interaction is also known as steric hindrance. In fact , it is so rare for cis double bonds to be more stable, that the few cases where this does happen are referred to as exhibiting the "cis-effect."

As for why trans-fatty acids (or trans-fats in common parlance) are harmful to humans, this general audience article indicates the problem is not a case of the stretched out trans-fats aggregating together to form clots as I had blindly guessed in class, but rather that the trans fats cause cholesterol and triglycerides to be produced when they are metabolized.

Lecture Notes

I have lecture notes to share with you. While these notes certainly do not represent the entirety of my lectures, they do represent the minimum information that I will go over. Also, the notes are essentially a condensed version of each chapter, so they should be very helpful to you when you are studying. The notes were created by a fellow Laney Professor, Cheli Fossum.

You can find the lecture notes here.

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.

Announcements Thursday 2/4/2010

The course website, at chem30b.blogspot.com is now up and running (finally) and is your go-to place for all materials and announcements for this class.

Quiz keys can be found at the course website chem30b.blogspot.com.

Tonights quiz will cover material from Tuesday's lecture (this will always be the case for quizzes, i.e. they will cover material discussed in the previous lecture.)

Reading/Homework: By know you should have read chapter 12, and done all the practice problems. Over the weekend, go ahead and read chapter 13 and do the practice problems for that chapter as well.
