Q:	Most chiral nitrogens are unstable and readily interconvert their stereochemistry spontaneously to form racemic mixtures. This process can be slowed to maintain the stereochemistry of the nitrogen atoms in which of the following ways?

increasing the pH of the solution

decreasing the size of functional groups on the nitrogen

increasing the temperature of the solution

increasing the steric hindrance of the functional groups on the nitrogen
