hello everyone,

1.Lactic acid

2. 2-pentanone

3. 2-butene

4. phenol

Now both phenol and 2-pentanone show tautomerism.

many institutes solutions say only 2- pentanone and some say both 2-pentanone and phenol.

The answer is only phenol. 2-pentanone will not show tautomerism due to the abscene of an alpha hydrogen atom.
