Learn alkene fundamentals: distinguish alkenes from aromatics, understand sigma and pi bonds and sp2 hybridization, and master naming rules that prioritize the alkene and include the longest chain.
Learn to classify cis/trans and e/z designations for alkenes, using vertical cuts and ranking rules to assign configurations and understand why trans is often more stable due to steric strain.
Explore how alkenes react with hydrogen halides via Markovnikov addition, forming halides, and why carbocation stability—via hyperconjugation and inductive effects—favors secondary over primary.
Explore dihalide addition to alkenes, an anti addition halogenation mechanism that forms bromonium ion intermediates and delivers bromine atoms on opposite faces, guided by carbocation stability and sterics.
Learn acidic hydration of alkenes: water adds under acid catalysis to give alcohols, with carbocation formation, possible hydride shifts, and 50/50 addition from either face, regenerating the acid catalyst.
Learn how hydrogenation of alkenes adds hydrogen gas over a platinum or palladium catalyst to convert double bonds to single bonds, via concerted syn addition on the catalyst bed.
Explore diol formation from alkenes via syn addition using osmium tetroxide and sodium sulfite to yield alcohols. Contrast anti addition via proxy acid and epoxide opening with the syn route.
Explore three lesser-used alkene reactions: oxidative cleavage of diols with periodic acid to yield aldehydes and ketones, and two carbene-forming methods to make three-membered rings.
Practice problems teach alkene mechanisms and synthesis, guiding you to predict the correct product from die halide addition and hydration routes, including hydroboration and oxymercuration.
Explore alkene synthesis through a problem set of worked solutions, focusing on regio- and stereochemistry, Markovnikov and anti-Markovnikov outcomes, rearrangements, and oxidative cleavage.
This course will cover all the basics for alkene properties and synthesis techniques. It is intended to be one of several affordable micro 1st semester organic chemistry courses. You will learn how to execute alkene (double bond) problems with ease and confidence. What you will get from this course:
- Improved grades in your class
- Lifetime access to tutorial videos on all alkene subjects including: naming, stability, stereochemistry, and all mechanisms and synthesis techniques learned in Organic Chemistry I.
- The ability to ask your own organic chemistry questions to the instructor with personalized feedback. I am an experienced university teacher and you can search for me on rate my professor using the name: Matthew Tomney.
- Video walk-through of solved problem sessions for your own practice and review.
