Write the structures for each of the following Acid-Base reactions. Used curved arrows to show of electrons in each reaction. (a) the reaction between a Lewis acid and an amine (b) the reaction between a Lewis acid and an alcohol
Tulung ate n illud aludke place in a single step. In the Sn2 reaction, the nucleophile attacks the a-carbon from the backside and displaces the leaving group with an inversion of configuration occurring at the carbon. In the E2 elimination reaction, strong base removes an acidic hydrogen from the B-carbon and an alkene is formed as the leaving group is expelled from the a-carbon. This elimination follows Zaitsey's rule whereby the more substituted alkene is generally formed. In E2 elimination,...
