Hey i'm studying for my chem exam & im having difficulty solving some problems. 1. 1,3cyclohexadiene + Br2= ? Here,should i treat it like a conjugated diene? Meaning that the Br molecules will have 1,2 and 1,4 additions on the diene and 2 products will be there? 2. 1,4cyclohexadiene + Br2 = ? Here should i t eat it like an isolated diene? & if so..where should the Br add? On which bond? Or will there be 2 products? With Br adding on the 1 double bond in the first & 4 double bond in the second? 3. When propylene is treated with bromine in methanol (CH3OH),two products are formed C3H6Br2 & C4H9BrO.Explain meachanistically how each are formed. Here,the first product is simple..its obtained by halogenation of alkenes..simple addition of the Br molecules on the pi-bond.But i wasn't able to determine how the second product is obtained? Obviously methanol has something to do with it..But what kind of reaction is it? We studied hyrohalogenation but nothing about alcohols & halogens together. 4. 1,2-dimethylcyclopentene + BH3 + H2O2/NaOH = This gives us the same product as direct hydrolysis since the alkene is symmetrical,correct? Any help in these questions would be greatly appreciated.They are just doubts that need clarifying :) & my exam is tomorrow.
