Extra Credit (5 points) Energy (C13), CI HI+CA, COM Time a. How many steps are there in the reaction mechanism? b. Label E, and AH® for each step C. Which step is rate determining? Why?
draw the most stabe conformer of 1-isopropyl-2,3-dimethyl-4-ethyl the chair confirmation
Draw the two chair conformations of each compound and label the substituents as axial and equatorial. In each case, determine which conformation is more stable. a. trans-1-ethyl-2-isopropylcyclohexane b. trans-1-ethyl-3-methylcyclohexane C. Cis-1-ethyl-4-methylcyclohexane d. cis-1-ethyl-3-methylcyclohexane
Please explain how you choose axial and equatorial connections and Please label which are axial and equatorial? its hard to tell from other posts, thanks. 13. D-Pinitol is an interesting hexahydroxy cyclohexane, whose structure is shown below. Draw the two chair conformations that are in equilibrium for D-pinitol, Circle the most stable conformation. но он но-- но --он он
Help Organic Chem part 4 Cyclohexane Conformations Put your model of cis-1,3-dichlorocyclohexane into a chair conformation. Sometimes the easiest way to do this is by adjusting it to make the axial bonds alternate up and down. Now convert it to the other chair structure, asking the instructor for help if needed. Is the second conformation still cis or is it trans? Are the two conformations the same or are they different? Draw chair structures of both conformations making sure to...
Please answer in detail 4. (a) Draw the structure of the two chair forms of methylcyclohexane. Draw in all bonds (even the C-H bonds). Be sure the axial and equatorial bonds are shown correctly. On the appropriate structure, indicate the 1,3-diaxial interactions involving the methyl group. (b) Which is more stable, trans-1,3-dimethylcyclohexane or cis-1,3-dimethylcyclohexane? Why?
with explanation 1) Draw a chair conformation of cyclohexane. Then, draw and level properly all axial and equatorial positions on chair form of cyclohexane. 2) Draw chair, half-chair and boat conformations of ethyl cyclohexane and draw an energy diagram to explain their relative stability: 3) Draw two possible chair conformations for each of the mono-substituted cyclohexanes and determine their relative stability with proper explanation. OH 4) Draw two possible chair conformations for each of the di-substituted cyclohexanes and determine their...
Disubstituted Cyclohexanes Chem 2511/2611 - Chapter 4 Draw both chair conformations for each cyclohexane molecule. 2. On each chair conformation, label the methyl groups as axial/equatorial and upkdown. 3. Label the lowest energy contormation if there is one. Cis or Trans Cyclohexane Chair Conformations 2
