Solution
Shape selective catalysis is exhibited by ZSM-5.
Explanation:
Shape selective catalysis is exhibited by zeolites like ZSM-5 because their catalytic action depends on the size of pores and cavities in the structure. Only molecules fitting into these pores can react, making the catalysis shape selective. Finely divided nickel, Lindlar’s catalyst, and platinised asbestos do not show shape selectivity in catalysis.
