The IUPAC name of the following molecule is
5,6-dimethylhept-2-ene
2,3-dimethylhept-5-ene
5,6-dimethylhept-3-ene
5-iso-propylhex-2-ene
The 4th higher homologue of ethane is
butane
pentane
hexane
heptane
C.
hexane
The molecular formula of ethane is C2H6 To get its fourth homologue, we have to add 4 x CH2 = C4H8 to it.
C2H6 + C4H8 = C6H14
C6H14 is the molecular formula of hexane. Thus, hexane is the fourth homologue of ethane.
