IUPAC Nomenclature of Organic Substituents (cyclo, sec-, iso-, tert-, hydroxy, phenyl, etc)
In today’s lesson, we are going to discuss naming different types of substituents on organic compounds, including both their name and drawing. Note that all substituents are highlighted in blue in the pictures below. Sometimes, some of these groups are not substituents, but rather they are the main functional family – it depends what other…

Geometric Isomers, Cis/Trans/E/Z Naming of Alkenes
In today’s lesson, we will be discussing the following topics: 1. What are Isomers? What are Geometric Isomers? 2. Using Cis/Trans/E/Z to name Alkenes When we draw organic compounds on paper, it is really only half the story – we haven’t taken into account their 3D structure at all! The direction of bonds within two…

Organic Nomenclature: Prefixes and Alkane, Alkene, Alkyne Families
In today’s lesson, we will be learning how to name and draw the following organic families (organic families are organic compounds that are categorized into “families” based on similar characteristics, such as having a carbon to oxygen bond, a double bond, a triple bond, a nitrogen group, or more), discussing homologous series, aliphatic vs aromatic…

Intro to Scalars and Vectors, Vector Notations, Operations, Dot and Cross Product, Unit Vectors
In today’s video, we will be introducing scalars and vectors, as well as different vector forms, vector operations, and unit vectors. Scalars are just regular old numbers, like time (3PM) or distance (5 kilometers). Vectors have a number associated with them, but also a direction, like displacement (5 km [North]) or acceleration (6 meters/second [down]).…

Ax=B Linear Systems, Gaussian vs. Gauss-Jordan Elimination, Rank and Pivot Positions
In today’s video, we will be discussing the following: 1. How to solve a system of equations using both Gaussian Elimination and Gauss-Jordan Elimination (including getting a matrix into Row Echelon Form (REF) and Reduced Row Echelon Form (RREF)). 2. What is the rank of a matrix and how to find it. 3. What are…
