Coordination bonds can be broken by decomposition of a coordination complex, or by the replacement of one ligand by another. When a coordination bond is broken, the lone pair of electrons stays with its original atom. That is to say, the is no formal electron transfer. Which of the following adheres to this rule regarding the decomposition of a coordination complex? H3N-BH3 ⇌ NH4+ + BH2- [Cr(OH2)6]3+ ⇌ Cr2+ + 5H2O + H2 + 1/2O2 [Cr(OH2)6]3+ ⇌ Cr3+ + 6H2O H3N-BH3 ⇌ BN + 3H2
