Are these cis/trans isomers? Why or why not?

Cis/trans isomers refer to molecules with the same molecular formula but different spatial arrangements. To determine if two molecules are cis/trans isomers, you need to compare their structural formulas and see if they have the same atoms and bonds but arranged differently. If they do, then they are cis/trans isomers.
The main difference between cis and trans isomers is the arrangement of functional groups or atoms around a double bond. In cis isomers, the functional groups are on the same side of the double bond, while in trans isomers, they are on opposite sides of the double bond.
Cis and trans isomers have different physical and chemical properties due to their different spatial arrangements. For example, cis isomers tend to have higher boiling points and melting points compared to trans isomers due to stronger intermolecular forces. They may also have different reactivities and biological activities.
Yes, a molecule can have both cis and trans isomers if it has multiple double bonds or chiral centers. In this case, the molecule will have both cis and trans isomers, as well as their enantiomers (mirror images).
To determine if a molecule has cis/trans isomers, you need to analyze its structural formula and look for the presence of double bonds or chiral centers. If there are double bonds, you can draw the possible spatial arrangements and check if they are cis or trans. If there are chiral centers, you can determine the possible stereoisomers by using the R/S system or Fischer projections.
