Answer» Solution :`CH_(3)-C-=CH+HOHunderset(He^(2+))overset(H_(2)SO_(4))to[CH_(3)-underset(OH)underset(\|)C=CH_(2)]toC_(3)-underset(O)underset(\|\|)C-CH_(3)` In the first setp, water ADDS on to propyne following Markovnikov rule to form propane-2ol. Being an enol, it is unstable and UNDERGOES TAUTOMERISATION to form stable propanone.
