Can imines tautomerise

Tautomers are structural isomers (constitutional isomers) of chemical compounds that readily interconvert. The chemical reaction interconverting the two is called tautomerization. This conversion commonly results from the relocation of a hydrogen atom within the compound. The phenomenon of tautomerization is called tautomerism, also called desmotropism. Tautomerism is for example rel… WebSep 2, 2015 · The correct answer is (a), and I'm curious if this is because to show tautomerism, there can't be any net charge.
