QJEEM25Ch1ed0: JEE Main 2025 Chemistry - Class 12 JEEM25Ch1ed0 Solution: The spin only magnetic moment ( ) value (B.M.) of the compound…

The spin only magnetic moment ( μ\mu ) value (B.M.) of the compound with strongest oxidising power among Mn2O3,TiO\mathrm{Mn}_2 \mathrm{O}_3, \mathrm{TiO} and VO is ____________ B.M. (Nearest integer).

Step-by-Step Verified Solution

Strongest oxidising power among the option is Mn2O3\mathrm{Mn}_2 \mathrm{O}_3 because of E∘\mathrm{E}^{\circ} value

amp;EMn+3/Mn+2∘=+1.57 Vamp;Mn+3→ d4 configuration amp;μ=24BMamp;=4.89BMamp;⇒5\begin{aligned}& \mathrm{E}_{\mathrm{Mn}^{+3} / \mathrm{Mn}^{+2}}^{\circ}=+1.57 \mathrm{~V} \\& \mathrm{Mn}^{+3} \rightarrow \mathrm{~d}^4 \text { configuration } \\& \mu=\sqrt{24} \mathrm{BM} \\& =4.89 \mathrm{BM} \\& \Rightarrow 5\end{aligned}
