Which of the following has diamagnetic character?

Question

Which of the following has diamagnetic character? (A) [ NiCl 4]2- (B) [ CoF 6]3- (C) [ Fe ( H 2 O 6)]2+ (D) [ Ni ( CN )4]2-

Tardigrade Admin · Accepted Answer

Ni in presence of CN- [Ni2+ in presence of CN -=[ Ar ] <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/efedce63fba448d8886d8de68b25b33f-.png" /> As [ Ni ( CN )4]2- has no unpaired electron. It is diamagnetic.

Q. Which of the following has diamagnetic character?

$[N i C l_{4}]^{2 -}$

$[C o F_{6}]^{3 -}$

$[F e (H_{2} O_{6})]^{2 +}$

$[N i (CN)_{4}]^{2 -}$

Ni in presence of $C N^{-}$

$[N i^{2 +}$ in presence of $C N^{-} = [A r]$

As $[N i (CN)_{4}]^{2 -}$ has no unpaired electron. It is diamagnetic.

Q. Which of the following has diamagnetic character?

[NiCl4​]2−

[CoF6​]3−

[Fe(H2​O6​)]2+

[Ni(CN)4​]2−

Ni in presence of CN− [Ni2+ in presence of CN−=[Ar] As [Ni(CN)4​]2− has no unpaired electron. It is diamagnetic.

$[N i C l_{4}]^{2 -}$

$[C o F_{6}]^{3 -}$

$[F e (H_{2} O_{6})]^{2 +}$

$[N i (CN)_{4}]^{2 -}$

Ni in presence of $C N^{-}$

$[N i^{2 +}$ in presence of $C N^{-} = [A r]$

As $[N i (CN)_{4}]^{2 -}$ has no unpaired electron. It is diamagnetic.
