Transition metals

Question 1

The chelate effect

Answer 1

Substitution of a unidentate ligand with a bidentate/ multi dentate ligand leads to a more stable complex as you have an increase in particles positive entropy change- reactions increase entropy more likely to occur- most stable.

Question 2

equation showing tallness reagent reacting with aldehyde in alkaline conditions

Answer 2

RCHO + 2 [Ag(NH3)2]+ + 3OH- –> RCOO- + 2 Ag + 4NH3 + 2H20
