Which of the following ions show higher spin only magnetic moment value?
(i) \[\ce{Ti^3+}\]
(ii) \[\ce{Mn2+}\]
(iii) \[\ce{Fe2+}\]
(iv) \[\ce{Co3+}\]

उत्तर
(ii) \[\ce{Mn2+}\]
(iii) \[\ce{Fe2+}\]
Explanation:
\[\ce{Mn^2+ (3d^5)}\] and \[\ce{Fe^2+ (3d^6)}\] have 5 and 4 unpaired electrons hence higher values of spin only magnetic moment as compared to \[\ce{Ti^3+ (3d^1)}\] and \[\ce{Co^2+ (3d^7)}\].
