Some Study Techniques

Hello awesome students,

Here are some links for you. These blogs, especially the first one, is an awesome resource. I have more blogs listed in the second page of the blog. You can reach it by clicking on the cyclohexane with the three lines (Menu) and then on the “Blogs to Look at” page.

Do’s and Don’ts 

Post about Isomers (bonus cat references)

Also this.  If you don’t look at anything else, look at this.

Favorite quotes: “Sometimes we’re going to come across questions where maybe we haven’t seen these reagents in exactly this combination before.  You’re going to say to yourself, “Uggg!  I swear, I have NEVER seen these reagents before.  I have NO IDEA what Dr. [azmanam] is trying to do here!”  And it may feel frustrating.  But we’re going to be required to take those reagents, combine them with what information we already know, and do something new and unique with it.”

Also, it’s okay if you sometimes feel like this.  Just as long as you keep doing this. 

Happy Studying!

Experiment 5: Extraction and Purification

The next week will be filled with extractions, recrystallizations, and even one synthesis!

Here are some resources to use!

A great post that sums up extractions.  Not everything is applicable, but it will give some good background on why we are doing certain things. Also, check out more of this blog! There’s stories of explosions, dead pigeons, and many hospital visits all while the author was under 18 in Communist-Poland.

What you don’t want to see…
Sublimation! (of ferrocene. your stuff should be white!)

Happy purifying!

Experiment 3: TLC

Awesome Students,

Here we come to our second way of determining purity of a substance /identifying what that substance is.*

TLC is extremely helpful and can be much faster than other ways of determining whether or not your product is pure or whether other side products have formed/starting material is still present.

Here’s some fun resources you can use!

Pretty Picture!
It may look ugly, but pure it is!

Another way to look at it.
An experiment at home!

A lovely almost-but-not-quite exhaustive look at TLC. Check out those charts!

Happy spotting!

*What do you think the first way is?

Experiment 1: Melting Point Determination/Calibration of Thermometer

Wonderful students,

The posts for each experiment will mostly be a gathering ground for resources on each topic, although this could also include important points I want you to remember from the lab lecture.

This experiment deals with measuring melting points using the MelTemp and calibrating your thermometer. The first two resources explain some of the concepts from the lab which will be useful in your discussion. The third resource will be helpful when making your calibration graph.
