But-1-yne on reaction with dil. $H_2SO_4$  in presence of  $Hg^{2+}$  ions at 333 K gives :

cdquestions Admin · Accepted Answer

The reaction shown is the hydration of but-1-yne (a terminal alkyne) in the presence of dilute sulfuric acid ( H₂SO₄ ) and Hg²⁺ ions (mercuric ions). In this reaction, but-1-yne undergoes Markovnikov's addition where the double bond of the alkyne reacts with water to form an aldehyde as the major product. But-1-yne reacts with dilute H₂SO₄ and Hg²⁺ ions at 333 K to form butanal (CH₃CH₂CH₂CHO) , which corresponds to option (A). Thus, the product is butanal (CH₃CH₂CH₂CHO) , making (A) the correct answer.
