    And why do group 2 catalysts make not so good catalysts?

    And does this have any relation to the collision theory?

    Thank you!

    transition elements have variable oxidation states.


    everything is mathematical.

    Group 2 metals do not make good catalysts mainly because their d orbitals don't interact with organic ligands well (if at all). Since most metal catalytic mechanisms involve coordination chemistry, this prevents group 2 from being able to do much. Like organic god said, the fact that group 2 usually only has one accessible oxidation state also plays a part, since many catalytic mechanisms involve oxidative addition or reductive elimination.

    So far as I know collision theory doesn't have anything to do with it.
