Question

Which one of the following complexes is diamagnetic in nature? (1) K 2[ Ni ( CN )4] (2) [ Ni ( H 2 O )6]( NO 3)2 (3) [ Co ( NH 3)6] Cl 3 (4) [ Pt ( NH 3)4] Cl 2 Select the correct answer (A) 1 and 2 (B) 2 and 3 (C) 1,2 and 4 (D) 1,3 and 4

As [ Ni ( H 2 O )6]( NO 3)2 has two unpaired electrons, so it will be paramagnetic, while rest complexes are diamagnetic in nature as they do not have any unpaired electron.

Q. Which one of the following complexes is diamagnetic in nature?
(1) $K_{2} [N i (CN)_{4}]$
(2) $[N i (H_{2} O)_{6}] (N O_{3})_{2}$
(3) $[C o (N H_{3})_{6}] C l_{3}$
(4) $[Pt (N H_{3})_{4}] C l_{2}$
