Step 1: Understand what butene is. Butene is a hydrocarbon with the formula C4H8, meaning it has 4 carbon atoms and 8 hydrogen atoms.
Step 2: Identify the structure of butene. Butene has a double bond between two carbon atoms.
Step 3: Learn about isomerism. Isomerism occurs when compounds have the same molecular formula but different structures or arrangements.
Step 4: Recognize the types of isomerism. One type is geometric isomerism, which occurs due to the restricted rotation around a double bond.
Step 5: Understand cis-trans isomerism. In cis isomers, similar groups are on the same side of the double bond, while in trans isomers, they are on opposite sides.
Step 6: Conclude that butene can have cis and trans forms because of its double bond, thus it exhibits geometric isomerism.
