One final question: why do you think AlCl3 or FeCl3 might be preferred for chlorination reactions and AlBr3 or FeBr3 for bromination reactions? Реакция хлорида алюминия с водой - … But why is it that the AlCl3/FeCl3 has to be ANHYDROUS? The mechanism for nitration of benzene: Step 1: Nitric acid accepts a proton from sulphuric acid and then dissociates to form nitronium ion. Alcohols and phenols react with active metals like sodium but it reacts with aluminium also which is not so reactive why?

Yes, but you’d likely get a small amount of contamination of the chloride along with the bromide. Save my name, email, and website in this browser for the next time I comment. The initiator/catalyst complex we identified is fundamentally different from the putative complex identified in the literature, which typically assumes that the AlCl3OH2 complex is the active catalyst.

They’re not the same type of compound. Question: The AlCl3/water Initiated Polymerization Of Isobutylene Is Carried Out Separately In Toluene Or Dichloromethane At –50°C A) Draw Out The Mechanism Of Initiation B) Which Solvent Will Give The Highest Polymerization Rate? Cyclohexane Chair Conformation Stability: Which One Is Lower Energy? SaralStudy helps in prepare for NCERT CBSE solutions for Class 12th chemistry. $\begingroup$ @Dissenter It means that the $\ce{H2O}$ isn't really generated from the reaction, but exists already. Nitration of benzene above 50c. Solution Construct the mechanism in terms of the three preceding steps.
