$Mn(II)$

Vedclass · Answer

(A) The paramagnetic character is directly proportional to the number of unpaired electrons.$A) Mn^{2+} : [Ar] 3d^5$ (Number of unpaired electrons = $5$)$B) Fe^{2+} : [Ar] 3d^6$ (Number of unpaired electrons = $4$)$C) Co^{2+} : [Ar] 3d^7$ (Number of unpaired electrons = $3$)$D) Ni^{2+} : [Ar] 3d^8$ (Number of unpaired electrons = $2$)Since $Mn^{2+}$ has the maximum number of unpaired electrons $(5)$,it exhibits the highest paramagnetic character.

$E^{\Theta }$	$V$	$Cr$	$Mn$	$Fe$	$Co$	$Ni$	$Cu$
$(M^{2+}/M)$	$-1.18$	$-0.91$	$-1.18$	$-0.44$	$-0.28$	$-0.25$	$+0.35$
