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
