Alkene Addition Reactions: Regioselectivity and Stereoselectivity Almost all reactions of alkenes we will learn about can be classified as addition reactions In an alkene addition
Read moreOpening Epoxides With Aqueous Acid Epoxides can undergo ring-opening with nucleophiles under acidic conditions. In this reaction, the epoxide oxygen is protonated first, making it
Read moreHydrohalogenation of Alkenes and Markovnikov’s Rule When hydrohalic acids (HCl, HBr, HI) are added to alkenes, addition reactions can occur, resulting in formation of a
Read moreHydration and Oxymercuration of Alkynes Via Keto-Enol Tautomerism Alkyne chemistry bears many resemblances to alkene chemistry, but in these first few posts on the subject,
Read moreAlkyne Hydrohalogenation – Addition of HX To Alkynes – HCl, HBr, and HI In the previous three posts on alkynes we’ve introduced some new reactions
Read moreHydration of Alkenes to Give Alcohols When alkenes are treated with aqueous acid (H3O+) they can be converted to alcohols. Formation of the new C-OH
Read moreBromination, Chlorination, and Halohydrin Formation from Alkenes Alkenes undergo halogenation when treated with Cl2, Br2 and (less commonly) I2 to give vicinal dihalides These reactions
