The primary way of preparing alkenes is through elimination reactions of alkyl halides and alcohols. The key difference between these two substrates is that the elimination of alkyl halides follows the E2 mechanism, while alcohols are dehydrated to alkenes via … Read more
The main Organic Chemistry 1 chapters in most US curricula go up to the reactions of alcohols. So, this summary will include synthesis practice problems on Alkenes, Alkynes, and Alcohols. If you need to practice SN1, SN2, E1, and E2 … Read more
In the previous post, we saw that ozonolysis is used to convert alkenes into aldehydes and ketones through the oxidative cleavage of the C=C double bond. Here are some ozonolysis practice problems for alkenes and alkynes, where you … Read more
Have you seen your professor talking about BH₃ and H₂O₂ and not quite understood what it is and when to use it?Ok, so, keeping it simple, we use BH₃ together with a peroxide to place an OH group on the … Read more
Alkenes react at low temperatures with either pure liquid bromine or a bromine solution in an organic solvent such as tetrachloromethane. During the reaction, the double bond breaks, and each carbon atom gains a bromine atom, forming a vicinal dibromide: … Read more
Halonium ions are structures where a halogen atom is connected to two alkyl groups: In your organic chemistry class, you are only going to worry about a specific type of halonium ion where the halogen is part of … Read more

There are direct ways of converting alkenes to amines covered in undergraduate organic chemistry textbooks, so a question like this is most likely meant to test your knowledge on multiple functional group transformations. The strategy here is to … Read more
Alkenes are converted to alkyl halides by the addition reactions of hydrohalic acids (HCl, HBr, HI). These are generally Markovnikov additions unless we direct the Br to the less substituted carbon atom radical addition using a peroxide catalyst: From reaction … Read more
Let’s discuss a few strategies for converting alkenes to carboxylic acids that allow to increase the length of the carbon chain, decrease it, and keep it the same as well: Alkenes to Carboxylic Acids: Keeping the Length of … Read more
