The top 7 organic chemistry sites for 2022

Hi Chemists–


Here are the top organic chemistry websites you need to visit. Organic chemistry is tough enough without having to search the whole web looking for more help.  So let us do the work for you. Here are our favorite sites to give you that edge in organic chemistry.  [By the way, these are all free sites!]

Japanese Spectral Database: On this site, you can type in almost any organic molecule (by mass, formula, or name) and will be able to view many of it spectra, including 1H NMR, 13C NMR, IR and mass spec.  Great resource, especially for the lab portion of the course.

Chemical Forums: Got a question that you want to run by a few friends that you haven’t met yet, or a homework problem you want a second opinion on?  This is the site.  Great (and pretty active) posting community where they will help you through a difficult problem or topic.  One word of caution–read the TOS before you go on.  The biggest thing is that they want you to have tried to figure it out a little yourself before posting on it.

Organic Chemistry Practice Exams: Shameless self-promotion alert!  We really do have the most comprehensive test bank on the internet.  It is all free (of course) and sorted by semester and difficulty of exam.  Most of the exams have answers too, which makes it a great place to sharpen your test taking skills. This is really a great study aide, if we do say so ourselves.

The Periodic Table Explained: Ok, most of us don’t like to admit that there are elements out there other than C, H, N, O and the halogens….but they do exist.  What happens when you find yourself outside of the universe of atoms we are comfortable operating with?  Go look them up on this periodic table.  Click on any of the atoms and a pop-up will tell you all about it.  Really nice for those moments when you have wondered into the realm of inorganic chemistry.

Organic Chemistry Name Reactions: A rose by any other name would smell as sweet”…true enough.  And yet if you don’t know what that name is, you might be totally in the dark.  That is where this site is helpful.  Should your professor toss out the name of an organic reaction, you can check this site to see what the heck that reaction is and what the mechanism is. Once you click on a named reaction, the page is crazy helpful as it has an explanation of the mechanism, a bunch of practical uses for the reaction and a ton of references.  Really helpful site.

Molecule of the Day: Two downsides here are that this is a little advanced and it has not been updated since 2011.  Two upsides are that it is kinda cool to look at some advanced stuff and figure out how the organic chemistry you know would work on this molecule AND (let’s be honest) undergraduate organic chemistry has not changed that much since 2011 so I think you’ll be fine.  Nice to look at some advanced chemistry to see how your knowledge can be used to understand something that has real life applicability.

So there you have it.  I wouldn’t go to these sites everyday, but it is a good way to take a peed at some really helpful stuff and see chemistry from a viewpoint other than your professor’s…..and they’re all FREE!!

Dr. Michael Pa got a bachelors degree in chemistry from Binghamton University, a masters degree in organic chemistry from the University of Arizona and a Ph.D. in organic chemistry from the University of Arizona. His research focus was on novel pain killers which were more potent than morphine but designed to have fewer side effects. There may even be a patent or two that came out of it. Prior to all of this, he was a chemist at Procter and Gamble. After all of that, he (briefly) worked as a post-doctoral assistant at Syracuse University, working on novel organic light-emitting diodes (OLEDs). In between, he did NOT compete at the 1996 Olympics, make the Atlanta Braves opening day roster, or become the head coach of the Indiana Pacers, as he had intended. #fail During this entire time, he always loved helping students, especially if they were struggling with organic chemistry. In 2006, Dr. Pa founded in order to make learning organic chemistry fast and easy. 14 years and about 60,000 students later we are still helping students to learn organic chemistry one reaction at a time at
