High and low field ligands
WebOverview of crystal field theory. According to crystal field theory, the interaction between a transition metal and ligands arises from the attraction between the positively charged … WebAnswer (1 of 5): For solving such questions the following problem solving strategy can be used in the given sequence: 1. Check the number of weak and strong field ligands, whichever are more will determine the outcome e.g. [Fe(H2O)2(CN)3(NH3)] is a low spin complex because of majority SFLs. 2. I...
