Vedclass · Answer

(D) Zeolites are aluminosilicates with a three-dimensional network structure. Statement $(I)$ is correct as they are shape-selective catalysts due to their pore structure.Statement $(II)$ is correct as they possess an $Al-O-Si$ framework.Statement $(III)$ is incorrect because zeolites are found in nature as minerals and can also be synthesized.Statement $(IV)$ is correct as they are widely used in the petrochemical industry for cracking hydrocarbons and isomerization.Therefore,statements $(I)$,$(II)$,and $(IV)$ are correct.

List-$I$ (Process)	List-$II$ (Catalyst)
$a$. Deacon's process	$i$. $ZSM-5$
$b$. Contact process	$ii$. $CuCl_2$
$c$. Cracking of hydrocarbons	$iii$. $Ni$
$d$. Hydrogenation of vegetable oils	$iv$. $V_2O_5$

The correct statements about Zeolites are:
$(I)$ They are good shape-selective catalysts.
$(II)$ They contain $Al-O-Si$ framework.
$(III)$ They are not found in nature.
$(IV)$ They are used as catalysts for cracking hydrocarbons in the petrochemical industry.
