Q

What are the steps for designating a chiral carbon S or R?

A
  1. Identify the asymmetric C carbon
  2. Assign priorities to the four substituents
  3. Draw the structure of the molecule viewed Dow the bond from C to the lowest priority group
  4. If arrangement of the remaining bonds from 1-3 appears clockwise assign R configuration, if anticlockwise assign S
