Here first addition reaction occurs according to Markonikov reaction than tautomerisation occurs to give acetone as follows

(H)_{3} C - C \equiv CH \to (H)_{2} O (CH)_{3} OH ∣ - C = (CH)_{2} \to Tautomerisation (CH)_{3} - C ∣ ∣ O - (CH)_{3} (Y)

Here first addition reaction occurs according to Markonikov reaction than tautomerisation occurs to give acetone as follows (H)3​C−C≡CH→(H)2​O(CH)3​OH∣−C=​​(CH)2​→Tautomerisation(CH)3​−C∣∣O−(CH)3​(Y)

Q. Predict the correct intermediate and product in the following reaction
$H_{3} C - C \equiv C H \to H_{2} O, H_{2} S O_{4} (X) in t er m e d ia t e \to (Y) p ro d u c t$

Here first addition reaction occurs according to Markonikov reaction than tautomerisation occurs to give acetone as follows
$(H)_{3} C - C \equiv CH \to (H)_{2} O (CH)_{3} OH ∣ - C = (CH)_{2} \to Tautomerisation (CH)_{3} - C ∣ ∣ O - (CH)_{3} (Y)$
