MCQ

The $IUPAC$ name of the Wilkinson 's catalyst $[RhCl(PPh_3)_3]$ is

A
Chlorotris (triphenylphosphine) rhodium $(I)$
✓
Chlorotris (triphenylphosphine) rhodium $(IV)$
C
Chlorotris (triphenylphosphine) rhodium $(O)$
D
Chlorotris (triphenylphosphine) rhodium $(VI)$

✓

Answer

Correct option: B.

Chlorotris (triphenylphosphine) rhodium $(IV)$

b
$\mathrm{Na}_{2}\left[\mathrm{Fe}(\mathrm{CN})_{5} \mathrm{NO}\right] \Rightarrow \mathrm{Na}^{+}\left[\mathrm{Fe}(\mathrm{CN})_{5} \mathrm{NO}\right]^{-2}$

$\therefore \quad \mathrm{x}-5+1=-2$

$\therefore \quad \mathrm{x}-4=-2$

$\therefore \quad x=+2$

$\therefore$ oxidation state of $\mathrm{Fe}$ is +2

$\mathrm{Na}_{4}\left[\mathrm{Fe}(\mathrm{CN})_{5} \mathrm{NOS}\right] \Rightarrow \mathrm{Na}^{+}\left[\mathrm{Fe}(\mathrm{CN})_{5} \mathrm{NOS}\right]^{4-}$

$\therefore \quad \mathrm{x}-5+1=-2$

$\therefore \quad x=+2$

The $0 .$ S of $F$ e in both the molecules in +2 .
