I count 5 structural isomers of hexane, #C_6H_14#..........

And these are.......

#(i)# #"n-hexane"#, #"H"_3"CCH"_2"CH"_2"CH"_2"CH"_2"CH"_3#

#(ii)# #"2-methylpentane"#, #"H"_3"CCH(CH"_3")CH"_2"CH"_2"CH"_3#

#(iii)# #"3-methylpentane"#, #"H"_3"CCH"_2"CH(CH"_3")CH"_2"CH"_3#

#(iv)# #"2,2-dimethylbutane"#, #"H"_3"CCH"_2"C(CH"_3")"_2"CH"_3#

#(v)# #"2,3-dimethylbutane"#, #"H"_3"CCH(CH"_3")CH(CH"_3")CH"_3#

The way to remember these is to sit down with a molecular model set, and actually make models of each isomer.
