Ketones and aldehydes are all around and inside us, from the strong smelling component of nail polish remover, acetone, to hormones in our bodies, to drug treatments for allergies, COVID-19, and even cancer! We’ve already learned a bit...

Nucleophiles, often referred to as "nucleus lovers," are chemical species that donate an electron pair to form a bond. They attack positively charged or electron-deficient atoms in a molecule, making them key agents in substitution and...

Electrophiles are electron-poor species, often possessing a positive charge or an empty orbital, making them highly reactive in seeking electron pairs from nucleophiles. Common examples include positively charged ions like

Markovnikov versus Anti-Markovnikov Additions

Chemistry doesn't always work perfectly, silly. Molecules are left over when one thing runs out! Also we never get all of the products that we thought we might by doing the math. You gotta know about the limiting reagents and the percent...

We know about a lot of different oxidizing and reducing agents that facilitate a variety of different transformations. But we haven't touched upon the precise transformation that can be achieved by diisobutylaluminum hydride, also known...

Practice REAL problems from actual past IIT/JEE exams with Professor Dave!

Once we get the hang of stoichiometric calculations, we get a curve ball. Limiting reagents? Not all of the reactants will react? We might not get as much product as we expect? Let's practice identifying the limiting reagent, calculating...

It's now time to dig into some olefination reactions, which generate olefins, or alkenes. The first is the McMurry reaction. It involves some rather mysterious titanium chemistry, via a mechanism that is not fully understood. Let's check...

We've learned about radical bromination for alkanes, but there is another method of radical bromination that can be applied to allylic and benzylic systems. This utilizes the reagent NBS, and it can be a useful synthetic technique. Let's...
