alpha-hydrogen atom and keto-enol tautomerism
The following is an extract from my book-
For an aldehyde or a ketone to exhibit keto-enol tautomerism, it is essential that it must have atleast one $\alpha$-hydrogen atom. Thus, acetophenone, ...

Hydrogenation stereochemistry-Pd,Pt, Ni catalysts
When my textbook talks about hydrogenation using Pt, Pd or Ni heterogeneous catalysts, it never mentions if it is anti or syn addition.
It simply jumps on to say that for alkynes, NiB2 (P-2) catalysts ...
