What To Expect in Organic Chemistry

August 28, 2017 By Leah4sci

what to expect in orgo

Organic chemistry is one of the most difficult sciences you’ll take in undergrad. Many students fail and have to take it again. You’ve heard the rumors. Perhaps you don’t believe them, or perhaps you’re terrified. But what can you actually do about them? The first step to conquering an unknown beast is understanding it. By […]

Carbocation Stability and Ranking

October 19, 2016 By Leah4sci

Carbocation Stability and Ranking Tutorial by Leah4Sci

Carbocations arise so frequently in Organic Chemistry that recognizing them must become second nature. After reading this tutorial, you should be able to eyeball a molecule and determine where a carbocation is likely to form as well as its potential stability. This will help you master carbocation intermediate reactions down the line including Markovnikov alkene addition […]

Naming Organic Compounds Practice Problems with PDF Solutions

September 15, 2022 By Leah4sci

alkane naming practice

Naming organic compounds (aka IUPAC Nomenclature) will show up early in Organic Chemistry 1 and will follow you for the remainder of Orgo 1 AND Orgo 2. For example, when you’re asked to react [molecule name] with [molecule name], or to synthesize [molecule name]. If you’re here hoping to learn via practice but don’t yet […]

Drawing Chair Conformations and Ring Flips for Cyclohexane

October 3, 2014 By Leah4sci

Drawing chair conformations and ring flips for cyclohexane

Studying chair conformations is likely one of the trickiest visual topics in organic chemistry, perhaps second only to Fischer projections. Not only are you required to learn a 3-dimensional concept, but you also have to manipulate that 3-D molecule on 2-dimensional paper. The average orgo student is not an artist, making this topic even trickier. […]
