Predict the product of the reaction mechanisms. Identify the electrophile and nucleophile in each reaction. Propose a mechanism for each reaction below. This means show curved arrows. You may want to fill in any nonbonding electrons. Show an example of each of the following types of reactions and explain why it is that type: Addition elimination Rearrangement Substitution

CH.CH,OH, d. CH.CH Does the equilibrium favor the reactants or products in each substitution reaction? a. CH,CH-NH, + Br -- CH,CHBr + NH b. n + ON ~ ON + r 7.6 Identify the nucleophile and leaving group and draw the products of each reaction...
4. In each case below identify: (a) the leaving group (b) the nucleophile, (c) and if the reaction is an Syl reaction or Sn2 reaction. (d) Draw the products of the following substitution reactions. NaSH DMSO MeOH H- Br NaCN DMF
4. In each case below identify: (a) the leaving group (b) the nucleophile, (c) and if the reaction is an Snl reaction or Sn2 reaction. (d) Draw the products of the following substitution reactions. NaSH DMSO MeOH H- Br NaCN DMF
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,...
