Show Answer
Answer:
Correct Answer: A
Solution:
$ \underset{But-1-yne}{\mathop{CH_3-CH_2-C\equiv }}CH+H_2O\to $
$ [ CH_3-CH_2-\overset{OH}{\mathop{\overset{|}{\mathop{C}}}}=CH_2 ]\underset{tautomerism}{\mathop{\xrightarrow{\text{keto-enol}}}} $
$ \underset{Butan-2-one}{\mathop{CH_3-CH_2-\overset{O}{\mathop{\overset{||}{\mathop{C}}}}-CH_3}} $
