Question

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

CH3 – S – CH2 – CH2 – CH3

And 

\[\begin{array}{cc}
\phantom{.....................}\ce{CH3}\\
\phantom{................}/\\
\phantom{}\ce{CH3 - S - CH}\\
\phantom{...............}\backslash\\
\phantom{....................}\ce{CH3}
\end{array}\]

Short/Brief Note

Solution

In the above structures, both have the same functional group (thioether/sulphide), but there is a difference in the arrangement of atoms in the main chain. So they can exhibit chain isomerism.
