Uracil, U, may undergo amide-imidic acid tautomeric shifts because any nuclear instability the molecule may have from the lack of formal aromaticity is compensated by the cyclic-amidic stability.
Uracil may undergo amide-imidic acid tautomeric shifts because any nuclear instability is compensated by the cyclic-amidic stability. The molecule may have from the lack of formal aromaticity any nuclear instability. Uracil is U.
