Which of the following compounds can show cis-trans isomerism?

Which of the following compounds can show cis-trans isomerism?

Step 1: Understand what cis-trans isomerism is. It occurs in compounds with a double bond where the groups attached to the double-bonded carbons can be arranged differently.
Step 2: Identify the compound in the question. In this case, we are looking at 2-hexene.
Step 3: Check if 2-hexene has a double bond. Yes, it has a double bond between the second and third carbon atoms.
Step 4: Look at the groups attached to the double-bonded carbons. In 2-hexene, the groups can be arranged on the same side (cis) or opposite sides (trans).
Step 5: Conclude that since 2-hexene has a double bond and different groups can be arranged, it can show cis-trans isomerism.
