Displayed formula for propene, which option is correct?

Explanation:
Propene is an alkene with three carbon atoms and the formula C3H6, so its displayed (structural) formula must show three carbons connected with a C=C double bond. The correct arrangement is a CH2 group double-bonded to a CH group, which is single-bonded to a CH3 group: CH2=CH-CH3. This structure matches three carbons and a double bond, which is exactly what propene is. The other options would depict different carbon counts (two for ethene, four for butene, five for pentene) and thus aren’t propene.
