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...
Cyclohexane: 1.Make a boat conformation. 2.Then a chair conformation In which case are the C-H bonds on neighboring carbons eclipsing the most? 3. In which case do the H atoms on C1 and C4 approach each other most closely? 4. Based on what you saw above, which will be the most stable conformation of cyclohexane? Draw both conformations
