Of the complexes, [ti(h2o)6]2+, [v(h2o)6]2+, [mn(h2o)6]2+, [ni(h2o)6]2+, which would have the least intense peaks in the uv spectrum
Accepted Answer
[Mn(H2O)6]2+ would have the least intense peaks in the UV spectrum. This is because Mn2+ has a d5 electronic configuration, meaning it has a half-filled d orbital. Half-filled and fully-filled d orbitals are particularly stable, making it harder for electrons to transition to higher energy levels (d-d transitions) that are responsible for UV-Vis absorption. The other complexes ([Ti(H2O)6]2+, [V(H2O)6]2+, and [Ni(H2O)6]2+) have partially filled d orbitals, leading to weaker stabilization and more readily occurring d-d transitions, resulting in more intense UV-Vis peaks.
