use the drop - down menus to identify the following structures as a cis isomer or trans isomer.

use the drop - down menus to identify the following structures as a cis isomer or trans isomer.
Answer
Explanation:
Step1: Recall isomer - definition
Cis - isomers have similar groups on the same side of the double - bond, trans - isomers have similar groups on opposite sides of the double - bond.
Step2: Analyze first structure
In the first structure, the two alkyl groups are on the same side of the double - bond, so it is a cis - isomer.
Step3: Analyze second structure
In the second structure, the two alkyl groups are on opposite sides of the double - bond, so it is a trans - isomer.
Answer:
First structure: cis Second structure: trans
