Question

Draw a nonsubstituted alkane that can exist as one of only two isomers.

Answer 1

An example of nonsubstituted alkane that can exist as one of only two isomers is Butane with molecular formula $C_{4} H_{10}$. 

Isomers are those having the same molecular formula but different chemical structure.

Non-substituted alkane means it is not substituted by any other atom.It has only carbon and hydrogen atoms attached to it.

Answer 2

The nonsubstituted alkane that can exist as one of only two isomers is butane.
