The stepwise formation constants for complexes of NH 2 CH 2 CH 2 NH 2 (en) with

Question:

The stepwise formation constants for complexes of NH2CH2CH2NH2 (en) with [Cu(OH2)6]2+(aq) are log Kf1 = 10.72 and log Kf2 = 9.31. Compare these values with those of ammonia given in Exercise 7.19 and suggest why they are different.


Data from Exercises 7.19.

The stepwise formation constants for complexes of NH3 with [Cu(OH2)6]2+(aq) are log Kf1 = 4.15, log Kf2 = 3.50, log Kf3 = 2.89, log Kf4 = 2.13, and log Kf5 = −0.52. Suggest a reason why Kf5 is so different.
