Predict the correct intermediate and product in thefollowing reaction

1.	Predict the correct intermediate and product in thefollowing reaction : H_3C-C-=CH underset(HgSO_4)overset(H_2O, H_2SO_4)to underset"(A)""Intermediate" to underset"(B)""Product"
Answer» `A:H_3C-undersetunderset(OH)\|C=CH_2 ""B:H_3C-undersetunderset(SO_4)\|C=CH_2` `A:H_3C-undersetunderset(O)(\|\|)C=CH_3 ""B:H_3C-C-=CH` `A:H_3C-undersetunderset(OH)(\|)C=CH_2 ""B:H_3C-undersetunderset(O)(\|\|)C-CH_3` `A:H_3C-undersetunderset(SO_4)(\|)C=CH_2 ""B:H_3C-undersetunderset(O)(\|\|)C-CH_3` SOLUTION :Markovnikov's addition of `H_2O` occurs. `CH_3-C-=CHunderset(HgSO_4//H_2O_4)OVERSET(H-OH)to underset"Intermediate (A)"(CH_3-undersetunderset(OH)\|C=CH_2) overset"Tautomerises"to underset"Aceton"(CH_3-undersetundersetO(\|\|)C=CH_2)`
