The next higher homologue of C6H14 is C7H16.
A homologue is a member of a series of compounds that have the same general formula but different molecular weights. The members of a homologous series are related by the addition of a methylene group (CH2) to the parent compound.
In the case of C6H14, the parent compound is hexane. The next higher homologue is heptane, which has the formula C7H16. Heptane is a colorless, flammable liquid that is used as a fuel and solvent.
The other options are not correct because they do not have the same general formula as C6H14. Option A, C7H14, has one more carbon atom than C6H14, but it has the same number of hydrogen atoms. Option B, C7H12, has one less carbon atom than C6H14, but it has the same number of hydrogen atoms. Option C, C6H12, has the same number of carbon atoms as C6H14, but it has two fewer hydrogen atoms.
Therefore, the next higher homologue of C6H14 is C7H16.
