4. Label all stereocenters in the following molecules. How many stereoisomers are
possible for each molecule? To be sure, draw each proposed steresoisomer, and
check to ensure it is unique.
CHOS
CH, CH:CH-(-CH. CH

Think about how you can use le chatelier’s principle to find possible solutions to the design problem. describe at least two ways to increase the yield (amount) of ammonia based on this principle.

Compare and contrast physical changes with chemical changes.
