Expert Solution

Step 1 Introduction

a) Alkynes undergo various reactions. They undergo addition with HCl, where Cl is substituted at the highest substituted carbon atom, according to Markonikov's rule.

b) They undergo a reduction with H₂ in the presence of Lindlar catalysts. Lindlar catalyst consists of BaSO₄ coated with Palladium metal that is poisoned by quinoline.

c) In the presence of Sulphuric acid and Mercuric sulfate, alkyne gets converted to a ketone where one carbon is converted into carbonyl carbon.
