Question
The correct statements among the following are :
A. Basic vanadium oxide is used in the manufacture of $H_{2}{SO}_{4}$.
B. The spin-only magnetic moment value of the transition metal halide employed in ZieglerNatta polymerization is 2.84 BM .
C. The p-block metal compound employed in Ziegler-Natta polymerization has the metal in +3 oxidation state.

Choose the correct answer from the options given below:
Options
Solution
Sol. [Key Concept: Evaluate each: $V_{2}O_{5}$ (amphoteric, used for $H_{2}{SO}_{4}$), the Ziegler-Natta ${TiCl}_{4} + {AlMe}_{3}$ oxidation states, and ${Pd}^{2 +}$ ($4d^{8}$) in the Wacker process; C and D are correct.]
A. $V_{2}O_{5}$ is amphoteric. It is used in manufacture of $H_{2}{SO}_{4}$.
B. Ziegler natta catalyst is $\underset{+ 4}{{TiCl}_{4}} + \underset{+ 3}{{AlMe}_{3}}$
$${Ti}^{4 +}:3{\text{ }d}^{0}4{\text{ }s}^{0}\ \ ,n = 0,\ \mu = 0$$
C. O.S. of Al is +3
D. $\frac{{PdCl}_{2}}{+ 2}$ is used in wacker process
$${Pd}^{2 +}:4{\text{ }d}^{8}5{\text{ }s}^{0}$$
C and D are correct.
