15.9 ligand exchange reactions Flashcards
1
Q
rate the stability of complexes from different types of ligands.
A
multidentate > bidentate > monodentate
2
Q
why are multidentate complexes more stable?
A
increase in entropy: more moles of products than reactants
3
Q
what are the approximate values of ^H & ^S surroundings for a ligand exchange reaction?
A
~0 as num. of dative covalent bonds & type are the same
