Consider the statements
(A) In Zeigler-Natta catalyst, d-block central metal ion has spin magnetic moment of 2.84 BM.
(B) In Zeigler-Natta catalyst, p-block element has +3 oxidation state.
(C) Basic vanadium oxide is used in the production of \( \text{H}_2\text{SO}_4 \).
(D) Catalyst used in Wacker's process has central metal with \(d^8\) configuration.
Step 1: Analyze Statement A.
In Zeigler-Natta catalysts, which are primarily used in polymerization reactions, the d-block central metal ion typically forms complexes with alkyl or halide groups. The spin magnetic moment is related to the number of unpaired electrons in the metal ion, but 2.84 BM does not fit the usual range for Zeigler-Natta catalysts, where the magnetic moment is generally lower, and this statement is not correct.
Step 2: Analyze Statement B.
In Zeigler-Natta catalysts, the central metal ion is often a transition metal (e.g., titanium, vanadium) which can exist in a +3 oxidation state, particularly in the case of titanium in TiCl\(_3\), so Statement B is correct.
Step 3: Analyze Statement C.
Vanadium oxide (V\(_2\)O\(_5\)) is indeed used in the production of sulfuric acid (\( \text{H}_2\text{SO}_4 \)) in the Contact process, but this does not directly relate to the statement in the context of the Wacker process, and Statement C is not related to the Wacker process. Therefore, this statement is incorrect in context.
Step 4: Analyze Statement D.
In the Wacker process, the catalyst used is typically a palladium(II) complex with a \(d^8\) configuration, which is the correct configuration for palladium. This makes Statement D correct.
Step 5: Conclusion.
Thus, only Statements B and D are correct, making option (B) the correct answer.
