For the following Assertion and Reason, the correct option is:...
For the following Assertion and Reason, the correct option is:
Assertion: For hydrogenation reactions, the catalytic activity increases from Group to Group metals with maximum activity shown by Group elements.
Reason: The reactants are most strongly adsorbed on group elements.
Assertion: For hydrogenation reactions, the catalytic activity increases from Group to Group metals with maximum activity shown by Group elements.
Reason: The reactants are most strongly adsorbed on group elements.
Options
- AThe assertion is true, but the reason is false
- BBoth assertion and reason are false
- CBoth assertion and reason are true and the reason is the correct explanation for the assertion
- DBoth assertion and reason are true but the reason is not the correct explanation for the assertion
Correct answer
A. The assertion is true, but the reason is false
Step-by-step solution
The general trend for the activity for hydrogenation increases from left to right. In Hydrogenation reaction, catalytic activity depends on variable oxidation states as well as atomic size. Hence for hydrogenation reactions, the catalytic activity increases from a group 5 to group 11 metals with maximum activity shown by group 7-9 elements.
