Vedclass · Answer

(B) The correct matches are as follows:$A$. $V_2O_5$ is used as a catalyst in the Contact Process for the industrial preparation of $H_2SO_4$ from $SO_2$. Thus, $A-III$.$B$. $Fe$ is used as a catalyst in the Haber process for the preparation of ammonia from a $N_2/H_2$ mixture. Thus, $B-I$.$C$. $PdCl_2$ is used as the Wacker catalyst for the oxidation of ethyne to ethanal. Thus, $C-IV$.$D$. $Ni$ complexes are used to catalyze the polymerization of alkynes. Thus, $D-II$.Therefore, the correct matching is $A-III, B-I, C-IV, D-II$.

List-$I$ (Transition metal/Compound/complex)	List-$II$ (Catalytic Role)
$A$. $V_2O_5$	$I$. Preparation of ammonia from $N_2/H_2$ mixture
$B$. $Fe$	$II$. Polymerisation of alkynes
$C$. $PdCl_2$	$III$. Preparation of $H_2SO_4$ from $SO_2$
$D$. $Ni$ complex	$IV$. Oxidation of ethyne to ethanal
