Isomers have the same molecular formula but different structural formula. 

Linkage isomerism is not a type of structural isomerism. 

n-isomers, iso-isomers and neo-isomers will show chain isomerism. 

When two or more compounds with the same molecular formula differ in position of substituent or functional group, they are called positional isomers.
