A guide to organic chemistry mechanisms
The dreaded weed-out class. A pre-med’s worst nightmare. Students often approach organic chemistry with apprehension, and a particularly sore spot in the class is mechanisms. Arrows, electrons, charges, and structures all drawn out like a map. Now, make that 10 maps – or 20! What’s a pre-med to do?
Orgo 1 tips: organizing the acid-base basics
Acid-base chemistry is a fundamental unit in orgo that provides a platform for many of the other reactions you’ll learn about throughout the semester. Not only that, it’ll follow you to many other classes (like biochem and inorganic chem). If you’re still puzzling over what acids and bases even are, let’s take a minute to get everything straight. ...
An introduction to resonance
Arguably one of the most important topics you will learn in your organic chemistry course, resonance is something that seems like it makes absolutely no sense upon first glance. What does it mean, why should I care about it, and how do I use this information to supplement my understanding of organic chemistry at large? All great questions!
Steps for solving organic chemistry synthesis problems
The time has come. You are past the introductory chapters of your organic chemistry class and now must dive into one of the hard parts: synthesis problems. These types of questions can be intimidating at first because they rely on your knowledge of a variety of reactions and can be like little puzzles. However, there is no need to be scared. By ...
Simplifying MCAT Organic Chemistry
While Organic Chemistry makes up a smaller portion of the MCAT, understanding the distinctions between types of organic reactions is essential. This will outline several foundational strategies for tackling chemistry on the MCAT, without pure memorization. Having a strong comprehension of organic reactions will allow you to save valuable time on ...
Chromatography: purifying your understanding
Maybe you were studying for the MCAT or just in your college chemistry lab when it dawned on you: why are there so many different types of chromatography? What do they have in common and what are their differences?
Tips for success in organic chemistry courses
Organic chemistry is historically considered a “weed-out” class for pre-medical students and often the cause of much frustration for students. After spending 3 years during college serving as a teaching assistant and tutor for organic chemistry courses at my undergraduate university, here are some tips for studying for your organic chemistry ...
Drawing the chair conformation of a pyranose ring
In this blog post, we will complete the following example problem:
I just want to be a doctor, so does organic chemistry really matter?
Imagine: you’ve made it through your first semester or two of undergrad and weathered all the storms that come with this transition. And, now you find yourself facing a dreaded academic giant that has stricken fear in the hearts of scores of pre-medical students. A chemistry course unlike any other. If you are anything like most pre-medical ...
Orgo 2 strategies: “taking home” carboxylic acid derivatives
I’ve already covered how to easily manage carboxylic acid derivative formation and manipulation using the Reactivity Hill. Say we’re tired of whatever derivative we just created and want to bring the derivative back to its parent acid (the particular acid the derivative came from). There are two ways to “take home” any acid-derivative. We can ...
Golden rules to nuclear magnetic resonance spectroscopy (NMR) analysis: part 1
Nuclear magnetic resonance spectroscopy, or NMR, is a fundamental analytical technique used by chemists to determine the structure of organic compounds. Unlike other analytical techniques, such as infrared spectroscopy or mass spectroscopy, NMR allows for the complete interpretation of molecular structure and can be quantitative.
Two ways to determine equilibrium position in organic chemistry
A common exam question that comes up in both Orgo 1 and Orgo 2 requires students to determine a reaction’s equilibrium position. The question usually looks something like this:
Orgo 1 strategies: finding and comparing alkene hydration products
We all know Orgo 1 professors love stereoisomers. Consider the equation A + B = C. Most professors expect you to fill in the question mark with all possible products and then indicate the major product(s), while other professors may provide you a potential C and then ask you if the statement is True or False.
How to get oriented to organic chemistry: 7 pillars of the course
Organic Chemistry (OChem or Orgo) seems like a scary course. But it should not be if you know what to expect. This road map is your guide to orientate yourself to Orgo1. It teaches you about the main topics covered in Orgo1 in the typical order they are taught in class. So, take a breath and sit back as you read, skim, or view the images that ...
Orgo 1 strategies: protocol for acid-base problems
Determining which of two molecules is more acidic is tricky if you haven’t yet organized those factors that influence acidity. The protocol is a method I learned from my mastermind Orgo 2 professor to keep these ideas in order when they come into conflict. Namely: Size is more important than Electronegativity, which is more important than ...
The basics of retrosynthesis
People often dismiss organic chemistry as “all memorization”. I disagree – organic chemistry is just a series puzzles based on a few basic concepts (electronics, sterics, orbitals) that come together to answer almost any problem you might encounter on your homework or tests.
The Chemistry Tutor: nine tips to get you through orgo
Many students find organic chemistry to be one of the most daunting classes that they take during college. And they’re right––it’s not easy! But with some good study skills, it’s possible for anyone to succeed and become a master organic chemist.
