The optical absorption spectrum of $\left[\mathrm{Ti}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right]^{3+}$ has its absorption maximum at $20300 \mathrm{cm}^{-1}$. The magnitude of crystal field stabilization energy in $\mathrm{cm}^{-1}$ is
(a)8120
(b)16240
(c)24360
(d)50750
Answer
Answer: A ✓ checked by 4AB · confidence high
Explanation
d¹: CFSE = 0.4Δo = 0.4 × 20300 = 8120 cm⁻¹ (a).
