Correct option is D
The correct answer is Heptene.
- In a homologous series, each successive member differs from the previous one by a CH₂ unit.
- Hexene (C6H12) belongs to the alkene group, characterized by a double bond.
- The next member in this homologous series would have one additional carbon atom and two additional hydrogen atoms, making it Heptene (C7H14).
Why Other Options Are Incorrect:
- Pentane (C5H12): It is an alkane (single bonds only) and does not belong to the alkene group.
- Pentene (C5H10): It is an alkene, but it has fewer carbons than hexene, so it cannot be the next member.
- Heptane (C7H16): It is an alkane and does not belong to the alkene homologous series.
