For the following Assertion and Reason, the correct option is: Assertion: For hydrogenation reaction — d and f Block Elements Chemistry Question
Question
For the following Assertion and Reason, the correct option is: Assertion: For hydrogenation reactions, the catalytic activity increases from group-5 to group-11 metals with maximum activity shown by group 7-9 elements Reason: The reactants are most strongly adsorbed on group 7-9 elements (A) Both assertion and reason are false. (B) The assertion is true, but the reason is false. (C) Both assertion and reason are true, but the reason is not the correct explanation of assertion (D) Both assertion and reason are true and the reason is the correct explanation of assertion
Answer: B) THE ASSERTION IS TRUE, BUT THE REASON IS FALSE.
💡 Solution & Explanation
Group 7-9 elements of the periodic table show variable valencies so they have maximum activity because of the increase in adsorption rate.
