### Chemistry Exercise: Molecular Configurations #### Task 5: - **Objective**: Draw the following molecules in two different configurations about the double bond. Name the molecules and be sure to include the appropriate configuration (cis/trans or E/Z). If the structure cannot be drawn in two different configurations, explain why. #### Molecules: a. **H2C=CH2** b. **CH3CH=CHCH3** c. **Cl(CH3)C=CHCH3** #### Additional Notes: - The molecules listed involve examining isomers that arise from different spatial arrangements around the double bond, specifically cis-trans or E/Z isomerism. - **Diagrams Present**: The image includes sketches of the molecular structures, demonstrating potential spatial configurations around the double bonds. However, these diagrams are not clearly visible in the current transcription. Redraw them with clarity to emphasize the differences in isomerism for educational purposes. - **Evaluation**: Classify each structure using cis/trans (for simpler cases with hydrogens) or E/Z nomenclature (for cases with different substituents on each end of the double bond). If a molecule lacks the necessary substituents for isomerism around the double bond, such as identical groups on one side, provide an explanation. This exercise will assist students in understanding the concept of geometric isomerism, integral to the study of organic chemistry.

#### Molecules:
a. **H2C=CH2**
b. **CH3CH=CHCH3**
c. **Cl(CH3)C=CHCH3**
#### Additional Notes:
- The molecules listed involve examining isomers that arise from different spatial arrangements around the double bond, specifically cis-trans or E/Z isomerism.
- **Diagrams Present**: The image includes sketches of the molecular structures, demonstrating potential spatial configurations around the double bonds. However, these diagrams are not clearly visible in the current transcription. Redraw them with clarity to emphasize the differences in isomerism for educational purposes.
- **Evaluation**: Classify each structure using cis/trans (for simpler cases with hydrogens) or E/Z nomenclature (for cases with different substituents on each end of the double bond).
