Test: Motion in Combined Electric & Magnetic Fields (December 26) - NEET MCQ

IUPAC name of sodium nitroprusside Na₂[Fe(CN)₅NO] is sodium pentacyanonitrosyl ferrate (III) because in it NO is neutral ligand and the oxidation number of Fe is +3. Which is calculated as Na₂[Fe(CN)₅NO]
2×(+1)+x+5×(−1)+1×0 = 0
2 + x - 5 = 0
x - 3 = 0
x = + 3

The formula of complex hexamminecobalt (III) chloride sulphate is [Co(NH₃)₆]CISO₄.

The IUPAC name of [Ni(PPh₃)CI₂]²⁺ is dichloro bis (triphenylphosphine) nickel (ll)ion.

K2[OsCI5N] is named as potassium pentachlorozoosmate (VI)

DMG (bidentate and neutral) is not named correctly, acac, bipy and gly have correct names respectively.

Ionization isomers are identical except that a ligand has exchanged places with anion or neutral molecule that was originally outside the coordination complex.
Thus, in Ionization isomerism the central ion and the other ligands are identical.
So, according to the definition, Cl^- is replaced by NO^2- in the ionization sphere.
 [Cr(H₂O)₄Cl(NO₂)Cl] ---->  [Cr(H₂O)₄Cl(NO₂)]⁺ + Cl^-
[Cr(H₂O)₄Cl₂]NO₂ -----> [Cr(H₂O)₄Cl₂]⁺ + NO₂^-

When a di or polydentate ligand used its two or more d onor atoms to bind a single metal ion. It is said to be a chelate ligand. The number of such ligating groups is called the denticity of the ligand. Such complexes are called chelate complex tend to be more stable than similar complexes containing unidentate ligands.

The correct answer is 4.

Ans: c

Explanation:Pt(NH₃)₂Cl(NO₂)

m − 2 = 0 

m = +2 

(NH₃)₂ ⇒ Diammine 

Cl ⇒ Chlorido

NO₂ ⇒ Nitrito-N. 

So, IUPAC NAME: diamminechloridonitrito-N-platinum(II)

[Ni(dmg)₂] : bis (dimethylglyoximato) nickel (II)
