What will be the major product of following sequence of reactions?

Correct answer

2

Step-by-step solution

First step of the reaction involves acid base reaction to form n - Bu - C ≡ C - Li + .This is due to the presence of acidic hydrogen in the reactant Hex-1-yne. Second step involves nucleophilic substitution to form a higher alkyne. Third step involves hydrogenation of alkyne by using lindlar catalyst to form cis-alkene
