Understand that a terminal alkene is an alkene where the carbon-carbon double bond is located at the end of the carbon chain, meaning one of the double-bonded carbons is attached to only one other carbon atom.
Analyze each compound's structure to identify the position of the double bond:
- Ethene (C\_2H\_4) has only two carbons, so the double bond is necessarily between the two terminal carbons, making it a terminal alkene.
- Propene (C\_3H\_6) has the double bond between the first and second carbon atoms, so it is also a terminal alkene.
- 2-Butene (C\_4H\_8) and 2-pentene (C\_5H\_10) have the double bond between internal carbons (carbon 2 and 3), making them internal alkenes, not terminal.
