Question

COULD SOMEONE PLS NAME THIS CHAIR CYCLOHEXANE WITH THE R AND S CONFIGURATION.

Answer 2

You should practice your drawings :P There is only one chiral carbon in your cyclohexane with the hydrogen on a wedge (because it is pointing UP, UP is WEDGE) and the methyl group on a dash (because it is pointing down axial, DOWN is DASH). Use the kahn-ingold-prelog (spelling is probably wrong) to assign importance. The number 1 belongs to the carbon in-between your stereocenter and the carbon with two additional methyl groups; 2 is the carbon opposite it, 3 is the dash methyl, and 4 is the hydrogen. The least important should be on a dash however, so we switch the numbers between whatever is on a dash (the down axial methyl which was assigned 3) with the hydrogen (was 4) and then draw circular arrows from 1 to 2 to 3 (ignore the least important). This points in a counterclockwise (S) fashion, but since we had to switch priority earlier now we switch configuration to R as a result. If we had not needed to switch priority than we would not need to switch the configuration. If you need the S configuration simply change the down axial methyl with the up equitorial hydrogen at the stereocenter and you'll have the enantiomer. Don't forget to double check my assignments using the above information for accuracy!
