For which transition metal ions are low spin complexes impossible?

View answer and explanation

Correct option: D

All are correct

Option D (All are correct) is correct because low spin complexes require partially filled d-orbitals, and

Zn^{2+}

Zr^{2+}

, and

Ag^+

all have either completely filled or empty d-orbitals, making low spin configurations impossible.
