JEE Main2026Apr 6, Shift 1Chemistry

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 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

Solution

Evaluate each statement:

A. The catalyst in the Contact process is $V_{2} O_{5}$ , which is amphoteric, not basic. False.

B. Ziegler-Natta uses $TiCl_{4}$ (with $Al (C_{2} H_{5})_{3}$ ). Ti is in $+ 4$ oxidation state, configuration $3 d^{0}$ : no unpaired electrons, $μ = 0$ BM, not $2.84$ BM. False.

C. The p-block co-catalyst is the aluminium alkyl, where Al is in $+ 3$ . True.

D. The Wacker process uses $PdCl_{2}$ . Pd $^{2 +}$ has configuration $4 d^{8}$ , so $8$ electrons in the outermost $d$ orbital. True.

$∴$ C and D only.
