1. Explain with a couple of acyclic and cyclic examples (of 5 carbons or more) what is essential when establishing whether a molecule is chiral and achiral.

2. Provide a couple of examples with which you can illustrate the application of CIP rules to assign stereochemistry around a C = C double bond and a second molecule with at least two chiral centers.

3. Explain with a specific example Biot's law and how the specific rotation of a mixture of two enantiomers in unequal parts is determined and calculated.

4. Describe the importance of optical isomeria in chiral drugs.

I need to answer these questions based on stereochemistry! It the only information I have!! I answer the first question that says to explain the difference between geometric and configurational isomers.
