पर्याय

• Acid or bases 

• Zeolite 

• Platinum 

• Zeigler-Natta catalyst

Answer 1

Shape selective catalysis is a reaction catalysed by Zeolite.

Explanation:

Zeolites are shape selective catalyst. Their general formula is

M_x/n [(AlO₂)_x · (SiO₂)_y] mH₂O

where M = Na⁺, K⁺ or Cr²⁺

n = charge on cation

m = number of molecules of water of crystallisation

Zeolites' response selectivity depends on the size of their pores and cavities.
