I came across a question where $\ce{R-CH2-NH2}$ and $\ce{R-NH-CH3}$ are considered as functional group isomers but not as metamers.

If I'm not wrong, metamers compounds which have same molecular formula but different number of carbon atoms on a functional group (for example, $\ce{CH3-CH2-O-CH2-CH3}$ and $\ce{CH3-O-CH2-CH2-CH3}).$

So, shouldn't the compounds given in start of the question be metamers considering the fact that the '$\ce{NH}$' has different number of carbon atoms on either side in the two compounds, and if not, why so?

Then shouldn’t ethanol and dimethyl ether be metamers as well...but they are not. [Compounds having the same molecular formula but different number of carbon atoms (alkyl groups) on either side of functional group (i.e., -O-,-S-, -NH-, -C(=O)-) are called metamers and the phenomenon is called metamerism.]- Wikipedia. – Muskaan May 20 '20 at 07:11

Does this answer your question? Which is the correct definition for metamers (or metamerism)? – Aniruddha Deb May 20 '20 at 08:13
