What are the chair conformations and what do liked when the ring is flipped? also which conformation is more stable? 3) Write for Each of the following Molecules, Both chair Conformations possible and determine which is more stable. Troms-1-methyl-2- Ethyl cyclohexane staLc Trans Lis-1-Methyl-3- Etheyd Cyclohexane
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...
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
(2) Cyclohexane (CH) has two conformations, i.e. the chair conformation (e) and boat conformation (b). At 298 °K, the chair conformation (e) is at the ground state with energy = 0; and the boat conformation (b) is at the energy level of 22,000 J/ mol. (i) Calculate the molecular partition function (q) of cyclohexane at 298 ®K. (ii) Calculate the Boltzmann distribution (the most probable distribution) of the two conformations, and respectively. (iii) Compare these two conformations, which conformation is...
