Idea ! Though there might be a better way out; nevertheless.....

H-Câ‰¡C-H --(Na)--> HCâ‰¡CNa ---(CH₃X)--> HCâ‰¡C-CH₃ ----(Lindlar's)--> C=C-C ---(1mole H₂O addition)--> C-C(OH)-C ---(Tautomerise)---> Acetone.....

This is another way ----

acetylene + HgSO₄ /H₂SO₄ ---------> acetone

acetone + MeMgBr ----------> 2-propanol

2-propanol + O₂ + heat----------> acetone.

:) note in 3rd rxn no catalyst is required.

yes, for the no catalyst reaction, the name is "cumene hydroperoxide mechanism"

ok.
