Well, "heptane", C_7H_16 has NINE structural isomers..........

Explanation:

And, "octane", C_8H_18 apprarently has 18 structural isomers..........

And "nonane", C_9H_20 apparently has 35 structural isomers..........

And "decane", C_10H_22 has a whopping 75 structural isomers.

And this illustrates the structural complexity of the alkanes. Clearly, you would not be asked to identify all the structural isomers of even heptane. You might be asked to write a couple of structural isomers.
