How do you prioritize the groups on chiral centers?

Answer 1

The Cahn-Ingold-Prelog sequence rules assign priorities to the groups attached to each chiral centre.

This is an illustration of how relative priorities are set.

Answer 2

The priority of groups on chiral centers is determined by the atomic number of the atoms directly bonded to the chiral center. The higher the atomic number, the higher the priority. If there is a tie, prioritize based on the atomic number of the next atoms outwards until a difference is found. If necessary, compare the atomic numbers of the next atoms until a difference is found. If two groups are identical until a difference is found or one group ends, prioritize based on the next atoms in the chain until a difference is found.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
