What is the molecular formula for propene?

Explanation:
Propene is an alkene with three carbon atoms, so its formula follows the general idea for alkenes: CnH2n. With n = 3, that gives C3H6. The structural formula CH2=CH-CH3 shows three carbon atoms and six hydrogens, confirming the same result. Formulas with different numbers of carbons—like C2H4 for two carbons, C4H8 for four carbons, or C5H10 for five—describe other hydrocarbons, not propene.
