Structural Formulas for cis- and trans-Isomers of Pentene-2

Pentene-2 is an alkene with the molecular formula C5H10. It has two carbon-carbon double bonds, and the double bond is located between the second and third carbon atoms. The cis- and trans- isomers of pentene-2 differ in the spatial arrangement of the substituents around the double bond.

The cis-isomer has the two identical substituents on the same side of the double bond, while the trans-isomer has the two identical substituents on opposite sides of the double bond.

Here are the structural formulas for the cis- and trans-isomers of pentene-2:

Cis-Pentene-2: ``` H H | | C = C | | H CH3 ```

Trans-Pentene-2: ``` H CH3 | | C = C | | H H ```

In the cis-isomer, the two hydrogen atoms are on the same side of the double bond, while in the trans-isomer, the hydrogen atoms are on opposite sides of the double bond.

Please note that the structural formulas provided above are simplified representations of the molecules and do not show the three-dimensional arrangement of the atoms. The actual molecules exist in three-dimensional space, with the substituents arranged around the double bond in a specific spatial orientation.

I hope this helps! Let me know if you have any further questions.
