Alkenes, of course, must have at least two carbon atoms since the central feature of an alkene is a carbon-carbon double bond. Build ethene (ethylene), propene (propylene) and 1-butene and compare them to the models online. Now reconnect your model of 1-butene to represent its constitutional isomer 2-methylpropene (isobutylene).
ethene propene 1-butene 2-methylpropene
ethene propene 1-butene isobutylene
