(14) Give the correct IUPAC namefor each of the following compounds. Be sure to include the correct stereochemical designation using the EZsystem for any alkene having stereochemistry. On the structure given, clearly indicate the priority assignments you usedto determine any EZ designations you made. Use the letter “a,” the word “Hi,” or the number “1,” to designate the high priority group. The EZ designation you give must be consistent with the priorities you assigned.A PERIODIC TABLE IS PROVIDED AT THE END OF THE TEST. You may separate the last page from the rest of the test, if you wish, to make it easier to use. a. b.2. (8) Draw the structure of:(E)-4-ethyl-2,3-dimethyl-3-heptene. 3. (7) The reaction of 1-methyl-1-vinylcyclohexane with HCl in ether converts it to 1-chloro-1-isopropylcyclohexane as shown in the following equation. Write the steps in the mechanismfor this process. Be sure to show the following:(1) the structure of any intermediates that are formed during the mechanism, (2), what, if anything, is added or lost during each step of the mechanism, (3) any non-zero formal charges found on the structures that you write. REMEMBER:You may not use any materials except those that are given in the equation.
