Observe the Newman projection of the next molecule along the bond shown in red with the front carbon the one bonded to "Cl". a) Draw one of the Newman projections of the molecule with a staggered conformation. b) Draw one of the Newman projections of the molecule with an eclipsed conformation.
Use flat representation of rings, not chair in the drawing. Determine the most and least stable. Consider the most stable chair for each of these isomers, and then draw the most stable and least stable isomer based on a comparison of the best chair for each one.
I still don't know in which direction (axial or equatorial) the hydrogens are in both chair conformations of MCHM. Can you please draw the two conformations including the hydrogens?
Consider the substituted cyclohexane shown in the ball-and-stick model. (See attached) Draw the second possible conformation in the chair form, and classifyit as more stable or less stable than the conformation shown in thethree-dimensional model ?
Do not give handwriting solution. Click on the two groups that are in contact with one another and destabilize this conformation by steric strain. It helps to build a model of the molecule. Thankyou!
Rank these conformations from least to most stable.
