Draw the major product that forms for the following reaction. Use a line structure which means that you should not draw in H atoms and should not enter C for carbons unless necessary. Convert your answer to the InChI format and enter it as your answer. Do not attempt to show stereochemistry. Cl₂ low temp.

1. Starting with the molecules shown below, perform three different sequential synthetic steps, showing the reagent (above the arrow) and the product (after the arrow) for each step. You may use any other molecules or reagents that you desire. Note that each reaction must be performed on the product of the prior step, and each product must be a stable, neutral, organic molecule. Work-up / protonation of anions / addition of water does NOT count as a reaction step (but you are welcome to show it). You are allowed to use more than one reagent in step, but if you do, the sequence of use must be numbered. If Example: 1) CH3MgBr OH РСС 1) LDA H. 2) H20 CH2CI2 2) EtCI Complete: HO

2. Draw the missing structure(s) in each of the following reactions. The missing structure(s) can be a starting material or the major reaction product(s). Structures you draw should take into account the regiochemistry and stereochemistry of electrophilic additions to alkenes. If a starting material + reagent will not react, write "No Rxn" in the product box. If a product can't be prepared from the reagent specified and any alkene, write "Not possible" in the reactant box. a) H-Br CH2Cl2
