$

Choose the correct answer from the options given below :

  1. A (A)-(IV), (B)-(III), (C)-(I), (D)-(II)
  2. B (A)-(III), (B)-(I), (C)-(IV), (D)-(II) Correct answer
  3. C (A)-(I), (B)-(III), (C)-(IV), (D)-(II)
  4. D (A)-(III), (B)-(IV), (C)-(II), (D)-(I)

Solution

<p>(A) $\mathrm{TiCl}_4: \mathrm{Ti}^{4+}: 3 d^0 4 s^0$ or $\mathrm{e}^0 \mathrm{t}_2^0$</p> <p>(B) $\left[\mathrm{FeO}_4\right]^{2-}: \mathrm{Fe}^{6+}: 3 d^2 4 s^0$ or $\mathrm{e}^2 \mathrm{t}_2^0$</p> <p>(C) $\left[\mathrm{FeCl}_4\right]^{-}: \mathrm{Fe}^{3+}: 3 d^5 4 s^0$ or $\mathrm{e}^2 \mathrm{t}_2^3$</p> <p>(D) $\left[\mathrm{CoCl}_4\right]^{2-}: \mathrm{Co}^{2+}: 3 d^7 4 s^0$ or $\mathrm{e}^4 \mathrm{t}_2^3$</p> <p>$\therefore$ Correct matching of tetrahedral complexes given in List-I with their electronic configuration given in List-II is</p> <p>(A)-(III); (B)-(I); (C)-(IV); (D)-(II)</p>
