Assign the absolute stereochemistry for each of the following molecules.
(f)

Complete the structure of each of these so that it matches the (R) or (S) configuration associated with the name.

(e)

Name the following alkynes according to the IUPAC rules of nomenclature.

(d)

In Chapter 12, we introduce the S_N2 reaction, a nucleophilic substitution reaction that proceeds with inversion. Confirm that inversion has occurred in each of the following examples by determining the absolute configuration of the chiral center in the reactants and products.

(a)

Assign the absolute stereochemistry for each of the following molecules.

(e)

Prioritize the substituents at each chiral center and then, by comparing them to the models you created in Section 6.3.2, label the absolute configuration as R or S.

(d)

Prioritize the substituents at each chiral center and then, by comparing them to the models you created in Section 6.3.2, label the absolute configuration as R or S

(f)

What is the configuration of each of the asymmetric centers in the following compounds?

c.

Indicate whether each of the following structures is (R)-2-chlorobutane or (S)-2-chlorobutane:
