Question

Identify the following pairs of molecules as either identical, enantiomeric, or diastereomeric.

The image displays chemical structures of organic compounds. There are four diagrams:

1. **Top Left Structure:**
   - Consists of a six-membered ring with two double-bonded oxygen atoms (ketones) and a methoxy group (OMe).
   - There is a CH₂OH group attached to the five-membered ring via a dashed bond, indicating stereochemistry.
   - The structure shows multiple methyl groups (CH₃) attached to the rings.

2. **Top Right Structure:**
   - Similar to the top left structure but is shown in a different stereochemical configuration.
   - It also includes a six-membered ring with two double-bonded oxygen atoms (ketones) and a methoxy group (OMe).
   - The CH₂OH group is attached with opposite stereochemistry compared to the top left structure.

3. **Bottom Left Structure:**
   - Displays a cyclohexene ring with an additional vinyl group (–CH=CH₂).
   - The ring shows a hydrogen atom (H) attached with bold wedge bonds, indicating its stereolocation.

4. **Bottom Right Structure:**
   - Also depicts a cyclohexene ring with a vinyl group, similar to the bottom left.
   - The hydrogen atom is shown with dashed wedge bonds, indicating a different stereochemical arrangement than the bottom left structure.

These diagrams illustrate structural isomerism and stereochemistry concepts in organic chemistry, highlighting how different spatial arrangements of atoms affect molecular identity and function.

Expert Solution
Step 1 Introduction interpretation

Interpretation- 

To identify all the pairs of molecules which are identical , enantiomeric, or diastereomeric -

 

Introduction- 

Identical compound- Identical compounds are that compounds are those compound which shown with all the atoms in the same spatial orientation. And conformers of identical compound are same compound as all the different rotations about single bond.

Enantiomeric compound- Enantiomeric compound are those compound which have mirror image of each other or having same connectivity but opposite three-dimensional space. 

Diastereomeric compound- Diastereomer are the compound which have the same type of stereoisomer and having non- identical mirror image .
