Which of the following will be the next member of the homologous series of hexene?

Heptene is the next member in the homologous series of hexene. In a homologous series, each successive member differs by a CH2 unit. Hexene (C6H12) adds one CH2 unit to become heptene (C7H14). Both belong to the alkene family, which contains carbon-carbon double bonds and follows the general formula CnH2n.
