For the transition state structure below, choose an organic reaction in which it is involved and give a chemical equation for your selected organic reaction that includes the following:

(i) structural formula(s) for the organic reactant(s); be sure to show stereochemistry appropriately when necessary

(ii) the experimental conditions (Give structural formulas for organic compounds. Give a chemical formula or inorganic reactants or catalysts . If heat and/or light is needed, be sure to indicate it appropriately.)

(iii) structural formula(s) for the major organic product(s); be sure to show stereochemistry appropriately when necessary. As we do for most organic reaction equations, the chemical equations that you give do not need to be balanced.

Read these directions carefully. Read these directions carefully. (It was worth repeating) For the reaction of an alkene with water in the presence of Cl2 shown below, fill in the details of the mechanism. Draw the appropriate chemical structures and use an arrow to show how pairs of electrons are moved to make and break bonds during the reaction. For this question, you must draw all molecules produced in each step (yes, these equations need to be balanced!). Finally, fill in the boxes adjacent to the arrows with the type of step involved, such as "Make a bond" or Take a proton away". MAKE SURE TO NOTICE THE QUESTIONS AT THE BOTTOM. If an intermediate or product is chiral, you only need to draw one enantiomer for this problem. For the product, you must draw both enantiomers and write "racemic" if appropriate.

Using arrows to show the flow of electrons, write a stepwise mechanism for the reaction given below. [If this reaction proceeds via a mechanism for free-radical chain reaction, give three termination steps and be sure to label each elementary step in your mechanism as either “initiation,” “propagation,” or “termination.”] Recall that HCl in H2O exists as H3O+ and Cl .
