Vedclass · Answer

(A, D) Reagent $(I)$ $(2Na/liq. NH_3)$ is a dissolving metal reduction that converts an alkyne into a $trans$-alkene $(Q)$.Reagent $(II)$ ($H_2/Pd/CaCO_3$ with quinoline,also known as Lindlar's catalyst) is a partial hydrogenation that converts an alkyne into a $cis$-alkene $(R)$.Reagent $(III)$ $(2H_2/Pd/C)$ is a complete hydrogenation that converts an alkyne into an alkane.Therefore,statement $(a)$ is correct as $Q$ is the $trans$-product,and statement $(d)$ is correct as $R$ is the $cis$-product.

Reactant $P$ (an alkyne) gives products $Q$ (trans-alkene) or $R$ (cis-alkene).
The possible reagents are:
$(I) \ 2Na/liq. NH_3$
$(II) \ H_2/Pd/CaCO_3$ (quinoline)
$(III) \ 2H_2/Pd/C$
Which of the following statements is/are correct with respect to the above conversion?
