QJEEM24Chea88: JEE Main 2024 Chemistry - Class 12 JEEM24Chea88 Solution: The spin-only magnetic moment value of the ion among and , that …

The spin-only magnetic moment value of the ion among Ti2+,V2+,Co3+\mathrm{Ti}^{2+}, \mathrm{V}^{2+}, \mathrm{Co}^{3+} and Cr2+\mathrm{Cr}^{2+} , that acts as strong oxidising agent in aqueous solution is _________ BM (Near integer).

(Given atomic numbers : Ti:22, V:23,Cr:24,Co:27\mathrm{Ti}: 22, \mathrm{~V}: 23, \mathrm{Cr}: 24, \mathrm{Co}: 27 )

Step-by-Step Verified Solution

The ion which acts as strong oxidising agent in aqueous solution is Cr2+:[Ar]4s∘3d4\mathrm{Cr}^{2+}:[\mathrm{Ar}] 4 s^{\circ} 3 d^4

μ=4(4+2)=4.89⇒5\mu=\sqrt{4(4+2)}=4.89 \Rightarrow 5
