Q. How many complexes among the following are paramagnetic

$[Mn (CN)_{6}]^{3 -} [Cr (H_{2} O)_{6}]^{3 +} [Co (en)_{3}]^{3 +}$ $[V (CO)_{6}], [Ni (NH_{3})_{6}]^{2 +} [Ni (dmg)_{2}]$ $[Pt (Cl)_{2} (NH_{3})_{2}] [Cu (NH_{3})_{4}]^{2 +} [Cu (CN)_{4}]^{3 -}$

$[Mn (CN)_{6}]^{3 -}, [Cr (H_{2} O)_{6}]^{3 +}, [V (CO)_{6}], [Ni (NH_{3})_{6}]^{2 +}, [Cu (NH_{3})_{4}]^{2 +}$
are paramagnetic due to the presence of unpaired electrons.

Q. How many complexes among the following are paramagnetic [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−
