The spin-only magnetic moment value of the transition metal halide employed in Ziegler-Natta polymerization is 2.84 BM. C. The p-block metal compound employed in Ziegler-Natta polymerization has the metal in +3 oxidation state. D. The number of electrons present in the outer most 'd' orbital of metal ha

  3. CC and D Only
  4. DB, C and D Only

Correct answer

C. C and D Only

Step-by-step solution

Statement A: Vanadium pentoxide ( V ₂ O ₅ ) is used as a catalyst in the manufacture of H ₂ SO ₄ by the Contact process. V ₂ O ₅ is an amphoteric oxide, not a basic oxide. Thus, statement A is incorrect. Statement B: The transition metal halide used in Ziegler-Natta polymerization is TiCl ₄ . In TiCl ₄ , titanium is in the +4 oxidation state with a 3 d ^0 electronic configuration. The number of unpaired electrons is zero, so its spin-only magnetic moment is 0 BM. Thus, statement B is incorrect. Statement C: The p-b
