Q: What type of isomerism is exhibited by 2-butene?

Solution: 2-butene exhibits geometric isomerism (cis/trans) due to the restricted rotation around the double bond.

Steps: 6

Step 1: Understand what isomerism is. Isomerism is when two or more compounds have the same formula but different structures.
Step 2: Identify the type of isomerism in 2-butene. 2-butene has a double bond between two carbon atoms.
Step 3: Recognize that double bonds restrict rotation. This means that the atoms attached to the double-bonded carbons cannot rotate freely.
Step 4: Learn about geometric isomerism. Geometric isomerism occurs when there are different arrangements of groups around a double bond.
Step 5: Identify the two forms of geometric isomerism: cis and trans. In the cis form, similar groups are on the same side of the double bond, while in the trans form, they are on opposite sides.
Step 6: Conclude that 2-butene can exist in both cis and trans forms, which means it exhibits geometric isomerism.
