Question

Shape – Selective catalysis is a reaction catalysed by

• A. Zeolites
• B. Enzymes
• C. Platinum
• D. Ziegler-Natta catalyst

Answer 1

Answer: (A)

Zeolites

Answer 2

Zeolite is a most widely studied shape selective catalyst. Shape selectivity of zeolite depends upon pore structure of the catalyst, pore size generally varies between 260 pm to 740 pm. Such catalysts are highly specific because molecules of only a particular size and shape enter pores and get adsorbed.
