Identify the correct statement:
A) Square planar complexes react following the associative mechanism unless steric effects prevent association.
B) The trans effect plays no role for ligand substitution in octahedral complexes.
C) The rate-determining step in inner sphere electron transfer is very frequently the bridge formation step.

Question

Quizplus · Accepted Answer

Square planar complexes, particularly those of d8 metals like Pt(II), often undergo ligand substitution via an associative mechanism, where a ligand approaches and forms a bond with the metal center before another ligand leaves. This is unless steric hindrance prevents the association of the incoming ligand.
