Drawing Chair Conformations and Ring Flips for Cyclohexane

October 3, 2014 By Leah4sci 96 Comments

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. […]

Sp3, Sp2 and Sp Hybridization, Geometry and Bond Angles

September 21, 2021 By Leah4sci Leave a Comment

Sp3, Sp2 and Sp Hybridization, Geometry and Bond Angles

Sp³, sp² and sp hybridization, or the mixing of s and p orbitals which allows us to create sigma and pi bonds, is a topic we usually think we understand, only to get confused when it reappears in organic chemistry molecules and reactions. When I took general chemistry, I simply memorized a chart of geometries and […]

Ionic, Polar Covalent and Non-Polar Covalent Bonding Tutorial Video

July 28, 2015 By Leah4sci 12 Comments

Orgo Basics video 1 bonding by Leah Fisch

Orgo Basics Video Series: Video 1 Your organic chemistry professor will take it for granted that you have a solid understanding of bonding. Specifically the chemical nature of ionic bonds, polar covalent and non-polar covalent bonds. These will be especially important once you start working through reactions because understanding bonds will help you recognize strong/weak […]

Organic Chemistry or Art Class?

September 7, 2021 By Leah4sci 2 Comments

Drawing organic compounds feels like art class

Wait, they never told me I needed art skills to draw organic molecules! You knew this was going to be a difficult class, and you were ready for it. You prepared to learn about atoms and electrons, reactions and mechanisms. Oh, the mechanisms! You start with Skeletal Structures, Then you get to Newman Projections, And […]
