Are tautomers always metamers?
That's interesting. Can you give me an example of tautomers that are also metamers?
Sure! An example of tautomers that are also metamers are the ketone-enol tautomers of hexan-2-one and hex-3-en-2-one. They differ by the location of a proton, and also by the length of the chain, since one has a six-carbon chain and the other a five-carbon chain.
