[ Mn ( CN )6]3-, [ Cr ( H 2 O )6]3+, [ V ( CO )], [ Ni ( NH 3)6]2+, [ Cu ( NH 3)4]2+ are paramagnetic due to the presence of unpaired electrons.

Q. How many complexes among the following are paramagnetic $[M n (CN)_{6}]^{3 -} [C r (H_{2} O)_{6}]^{3 +} [C o (e n)_{3}]^{3 +}$ $[V (CO)_{6}], [N i (N H_{3})_{6}]^{2 +} [N i (d m g)_{2}]$
$[Pt (Cl)_{2} (N H_{3})_{2}] [C u (N H_{3})_{4}]^{2 +} [C u (CN)_{4}]^{3 -}$

$[M n (CN)_{6}]^{3 -}, [C r (H_{2} O)_{6}]^{3 +}, [V (CO)], [N i (N H_{3})_{6}]^{2 +}, [C u (N H_{3})_{4}]^{2 +}$ are paramagnetic due to the presence of unpaired electrons.

Q. How many complexes among the following are paramagnetic [Mn(CN)6​]3−[Cr(H2​O)6​]3+[Co(en)3​]3+ [V(CO)6​],[Ni(NH3​)6​]2+[Ni(dmg)2​] [Pt(Cl)2​(NH3​)2​][Cu(NH3​)4​]2+[Cu(CN)4​]3−
