Expert Answer:
Chain isomers :
Compounds having same molecular formula but are different in the arrangement of carbon atoms in straight or branched chains are referred to as chain isomers. n-butane and iso-butane differ in the arrangement of carbon atoms and are therefore chain isomers.

Position isomers :
When two or more compounds with the same molecular formula differ in the position of substituent atom or functional group on the carbon atom, they are called position isomers.
