Final answer:
The organic compound with the given structural formula is propene, which is part of the alkene series and contains a carbon-carbon double bond. The correct answer to the student's question is Ethene.
Step-by-step explanation:
The name of the organic compound with the given structural formula is propene (also known as propylene). Propene, C3H6, is part of the alkene series which are hydrocarbons with at least one carbon-carbon double bond. Ethene or ethylene, C2H4, is the simplest alkene with a two-carbon chain and a single double bond.
As the chains grow longer, the next alkene in the series is propene with three carbon atoms, followed by butene which can have isomers due to its four-carbon chain. The manner in which the butene structure can vary includes different positions for the double bond or branching which leads to structural isomerism. Therefore, the correct answer to the student's question is B) Ethene.
