Question

Assertion :Zeolites are good shape-selective catalysts. Reason: Zeolites have honeycomb like structures.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

• The catalytic reaction that depends upon the pore structure of the catalyst and the size of the reactant and product molecules is called shape-selective catalysis.
  
• Zeolites are microporous aluminosilicates with the three-dimensional network of silicates in which some silicon atoms are replaced by aluminium atoms giving $Al-O-Si$ framework.They are good shape-selective catalysts.
• Zeolites are good shape-selective catalysts because of their honeycomb-like structures.
• Hence, both assertion and reason are correct and the reason is the correct explanation for the assertion.
