SCREENS 009 AM 27/2017Explanation / Answer
Ans 1 An R conformer has clockwise arrangement of substituents from high priority to low priority
Whereas the S has it anticlockwise
Since we can do just 4 subparts, let me help you out with first four!
1st structure is S , as you can see it is anticlockwise from alcoholic group to bromide
Second is R, clockwise, from OH to Br
Third is R, clockwise from Br to ethyl group
Fourth is S, anticlockwise from Br to ethyl .
