The correct statements among the following are.

A. Basic vanadium oxide is used in the manufacture of $\ce{H2SO4}$ .

B. 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 halide employed in Wacker process is 8.

Choose the correct answer from the options given below:

A and B Only

A, C and D Only

C and D Only

B, C and D Only

Answer and worked solution

Official answer: C

Each statement.

A: $\ce{V2O5}$ (the contact-process catalyst) is amphoteric, not basic. False.
B: The Ziegler-Natta halide is $\ce{TiCl4}$ , with $\ce{Ti^4+}$ ( $d^0$ ), so its moment is 0. False.
C: The p-block compound is $\ce{Al(C2H5)3}$ , with Al in the +3 state. True.
D: The Wacker catalyst is $\ce{PdCl2}$ , with $\ce{Pd^2+}$ ( $4d^8$ ), so 8 d electrons. True.

Correct: C and D.

(C)
