3. (10 pts) For each cyclohexane, draw both chair conformations and circle the conformation that is more stable (use the relative size of each substituent to determine which has more 1,3-diaxial strain) S-Bu NH2 t-Bu /25 pts
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...
