6. Using the trans effect series suggest synthetic routes to cis- and trans-[PtCl2(NH3)2] from [PtCl4] 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.
4. Propose two synthetic routes to trans-1-methyl-2-(methylthio)cyclohexane (below) from the starting compound (a) cis-1-chloro-2-methylcyclohexane; (b) trans-1-chloro-2- methylcyclohexane. SCH CH3 5. Rank each of the following groups of substrates in order of decreasing S 2 reactivity. a. b. C. CHỊCH,CH,CI, CHÚCI, (CH, CH) CHOI (CH3),CHCH,CH,Br, (CH3),CHCH,Br, (CH3),CHBr CHỊCH,CI, CH, CH,I, (CH,),CHCl, CH2CH2Br
7. Draw and label both cis and trans isomers of 1-ethyl-4-methylcyclohexane. (10 pt) a. For each isomer, draw the two possible chairs and indicate which of the two will be preferred and by how much (a lot or little). (5 pt) b. Which of the four is considered the most stable (label as "best") and which is least stable ("worst")? (3 pt) c. Clearly label 1,3-diaxial interactions, if present, in any of the conformations? (2 pt) Cis Trans
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...
