Displayed formula for ethene, which option is correct?

Explanation:
Ethene is the simplest alkene and has the formula C2H4. Its structure features a carbon–carbon double bond between two carbon atoms, with each carbon bearing two hydrogens, giving CH2=CH2. The displayed formula that shows two carbons connected by a double bond with two hydrogens on each carbon matches CH2=CH2, so it represents ethene. The other options would involve more carbon atoms (three for propene, four for butene, five for pentene) and thus show different formulas around the C=C bond.
