Step 1: Understand what alkenes are. Alkenes are hydrocarbons that contain at least one carbon-carbon double bond (C=C).
Step 2: Learn about isomerism. Isomerism is when two or more compounds have the same molecular formula but different structures or arrangements.
Step 3: Identify the type of isomerism in alkenes. Alkenes can show geometric isomerism, which is a type of stereoisomerism.
Step 4: Know why alkenes exhibit geometric isomerism. This is because the double bond between carbon atoms restricts rotation, leading to different spatial arrangements of groups attached to the double-bonded carbons.
Step 5: Recognize the two forms of geometric isomerism: cis (same side) and trans (opposite sides) configurations around the double bond.
