7 Using the trans effect series suggest synthetic routes to cis- and trans-[PtCl2(NH3)2] from [Pt(NH3)4]2+ as a starting material.
Draw the molecules cis-[PtCl2(NH3)2] versus trans-[PtCl2(NH3)2]. a) If you assume the NH3 groups rotate freely and the out of plane hydrogens do not lower the symmetry, what is the point group symmetry? b) If the NH3 groups do not rotate freely, what are the possible point groups? I have the drawn molecules just unsure how to find the point groups.

1. Propose synthetic routes to prepare the compounds from the shown starting materials in 2 steps. Use any reagents as necessary: OH U from OH
uiz Problems - Provide an answer for each in the space provided. 1. Suggest a reasonable series of synthetic transformations (i.e. a series of reagents and reaction conditions) to prepare cis-2-methylcyclohexyl acetate CA) from trans-2-methylcyclohexanol (this problem is worth 4 points) H3C CH3 A (target molecule)
Successful synthetic routes must contain a minimum of 4 steps and at least one reaction from each chapter (7,8,9). 7 - SN2, E2, SN1, E1 8 - Addition of Alkenes 9 - Addition of Alkynes You should provide the correct IUPAC name for each organic chemical used and produced in your chemical synthesis. USE (Z) - 2 - Propenyl - cyclohexane as a starting material. The end product does not matter, just make sure to use a technique from each...
