Question

8. (pls each) For the following molecules, draw both chair conformers resulting from a ring-riip. and then indicate which structure predominates at equilibrium (if either. When a group specified you must draw out the structure of that group for full credit (no abbreviations wioned here!). Either enantiomer of each is acceptable. a. 2-sopropyl-5-methylcyclohexanol (The methyl and hydroxyl groups are cls, and the isopropyl group is trans to both). b. cis-1-sobutyl-3-fluorocyclohexane C. (4 pts) Draw the more stable conformation of b. above as a Newman projection, and place the substituents on the circular "faces' of the projection, not on the bridges between them.

Answer 1

Ring Flipping OH and ch, are above sie is. and isotropyle group is below i e trans CH 3 . CH (6 CHAHC - C - CH3 F Ring pupping isobutyl group and F are is to each other

hope this helps!

@ We know the bulky group tende to attain equêtorial poste osition as there is less storic repulsion with other axial groupe and hijehagens etc. so the stable conformation of us - 1-isobutyl-3 fluoro- adohepaие. CH3-CHET (Hz Now, the Newmann projection is; CH-CH2-CH-CH3 Kindly check the numbering so that you can easily understand the correlation
