below:
$(iii)$ The pairs $(a)$ and $(b)$ and $(e)$ and $(g)$ exhibit position isomerism.
The pairs $(a)$ and $(c); (a)$ and $(d); (b)$ and $(c); (b)$ and $(d)$ exhibit chain isomerism.
The pairs $(e)$ and $(f)$ and $(f)$ and $(g)$ exhibit metamerism.
All primary amines exhibit functional isomerism with secondary and tertiary amines and vice$-$versa.
