Compounds with same molecular formula but differing int heir structures are said to be structural isomers. What type of strucutral isomerism is shown by

$C H_{3} - S - C H_{2} - C H_{2} - C H_{3}$ and

The two isomers which differ in the position of the functional group on the carbon skeletoon are called position isomers and this phenomenon as position isomerism.

Thus, (A) and (B) may be regarded as position isomers and further they cannot be regarded as metamers since metamers are those isomers which have different number of carbon atoms on either side of the functional group.

But here, the number of carbon atoms on either side of sulphur atom (functional group) is the same i.e., 1 and 3.
