Verified step by step guidance

1. Identify the type of isomerism: Look at the structures to determine if they are enantiomers, diastereomers, or identical.
2. For part (e), observe the orientation of the Cl substituents on the bicyclic structures. Check if they are mirror images or if one is a rotated version of the other.
3. For part (f), analyze the Fischer projections. Compare the positions of the OH groups to see if they are mirror images or if they differ at one or more chiral centers.
4. Consider the stereochemistry: For part (e), determine if the compounds are cis or trans isomers based on the position of the Cl substituents.
5. For part (f), determine if the compounds are enantiomers (mirror images) or diastereomers (differ at one or more chiral centers but are not mirror images).
