The complete reaction is shown below: <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/4f3d9bd7eb6b47ec830fd09fa54a1c7d-.png" /> Reduction of alkyne using Pd/C gives cis-alkene as major product whereas reduction by using Na in liquid, ammonia gives trans-alkene as major product.

Q. Consider the following reaction,

What does $A$ refers to?

$N a / liq \cdot N H_{3}$

$P d / C$

Both (a) and (b)

None of these

The complete reaction is shown below:

Reduction of alkyne using $P d / C$ gives cis-alkene as major product whereas reduction by using $N a$ in liquid, ammonia gives trans-alkene as major product.

Q. Consider the following reaction, What does A refers to?
