Draw the structure of the major organic product/s for each of the following reactions. Indicate the stereochemistry for each reaction, when appropriate. If multiple functional groups in the molecule react under the conditions, you may assume that enough reagents (excess) are added to react with all the possible functional groups. If enantiomers are generated, you may draw one and indicate “+enantiomer”. LOH 1.Na º 2.CH31 3.CO, HCI, AICIZ/ Cuci
