Document Summary
A full description of a reaction includes the name of the transformation, reactants, intermediates and products. Please fill up the box to complete these transformations. Clearly label which is the major product and which are the minor products. H2o2 mcpba peracids: hg(oac)2, nabh4, naoh (or other oh-) In the boxes, specify the necessary reagents (show either names or structures, or both) to complete the following transformations, and indicate the intermediate(s) formed, if there is any. The products shown should be the major products. Question 3 (20 points) the major product and one of the minor products of the following reaction is shown. (1) give detailed mechanism that supports the observed results. Hint: use hammond postulate. (2) draw structures for the other possible products. Initial protonation of alkenes lead to two carbocation intermediates (a and b). Hammond postulate states that the transition state for a given transformation resemble the reactant (intermediate) of the higher energy.
