Q65 / 180 · AIIMS 2004 · Chemistry

Assertion : Alcohols are dehydrated to hydrocarbons in the presence of acidic zeolites. Reason : Zeolites are porous catalysts.

  • A
    If both assertion and reason are true and reason is the correct explanation of assertion
  • Correct answer
    B
    If both assertion and reason are true but reason is not the correct explanation of assertion
  • C
    If assertion is true but reason is false
  • D
    If both assertion and reason are false.

Solution

Zeolites are shape-selective porous solid acid catalysts, their catalytic activity originates from the presence of highly acidic $A 1-O(H)-$ Si hydroxyl in the framework.

Hence, the correct answer is option: 'B'.
