See below...

Explanation:

For the compounds to be isomers they must have identical condensed formula.

Alkane with n C atoms : C_nH_(2n+2)

Alkene with n C atoms : C_nH_(2n)

Alkyne with n C atoms : C_nH_(2n-2)

The compounds clearly differs in the number of H atoms per molecule and hence cannot be considered as isomers.
