Fondly remembering graduate school and some of my instruments
I thought I would write a quick post about one of the instruments I used while I was in graduate school. The instrument was a viscous liquid dispenser, and we used to dispense liquid epoxy with it. It was a wonderful instrument made by Ipscot, and could be used for all sorts of other liquids

Organic Chemistry: There are only FOUR important IR peaks….that’s IT
Amazingly enough, IR is not used much by professional organic chemists. This is because all IR can show is different functional groups. Thus, IR cannot tell the difference between any of the molecules shown below: All of the molecules above will show an OH peak and various C-H stretches, but each spectra will look striking similar.

Beware of the bad acid trip: Know your strong acids
A problem we see students constantly running into is that they do not readily recognize strong acids. This is a terrible mistake and should never happen. You will need to quickly recognize strong acids and which atom they will be protonating. As far as strong acids go, you should immediately recognize the Magnificent Seven:

Organic Chemistry Help: Resonance
Hi Everybody–Resonance is one of those issues that you will have to deal with for both semester I & II organic chemistry. It is much better to have a solid understanding of it now, rather than have to worry about it later. The basic goal of resonance structures is to show that molecules can move

Organic Chemistry Help: Resonance and SN1/SN2
Hi everybody, I wanted to talk briefly today about resonance and sterics and how it can affect and SN1 or SN2. For background, I hope everyone knows when it comes to SN1 reactions, tertiary substrates are the fastest and primary substrates are the slowest (because of carbocation stability). Conversely, when it comes to SN2, it

Organic Chemistry Help: Retrosynthesis on an enolate
Hi everybody, one of the questions I hear alot is about enolate product. How do you do the retrosynthetic analysis on one? How do you even know it came from an enolate reaction? Here is an example to look at: As you can see here, a possible enolate product is an α,β-unsaturated ketone. When you see one of
