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 A and B Only
- B A, C and D Only
- C C and D Only
- D B, C and D Only
Answer & Solution
Correct Answer
(C) C and D Only
Step-by-step Solution
Detailed explanation
Statement A: Vanadium pentoxide (\(\text{V}_2\text{O}_5\)) is used as a catalyst in the manufacture of \(\text{H}_2\text{SO}_4\) by the Contact process. \(\text{V}_2\text{O}_5\) is an amphoteric oxide, not a basic oxide. Thus, statement A is incorrect. Statement B: The…
