QJEEM24Chce1a: JEE Main 2024 Chemistry - Class 12 JEEM24Chce1a Solution: A first row transition metal with highest enthalpy of…

A first row transition metal with highest enthalpy of atomisation, upon reaction with oxygen at high temperature forms oxides of formula $${\mathrm{M}}_2{\mathrm{O}}_{\mathrm{n}}$$ (where $$\mathrm{n}=3,4,5$$). The 'spin-only' magnetic moment value of the amphoteric oxide from the above oxides is _________ $$\mathrm{BM}$$ (near integer)

(Given atomic number: $$\mathrm{Sc}:21,\mathrm{Ti}:22,\mathrm{V}:23,\mathrm{Cr}:24,\mathrm{Mn}:25,\mathrm{Fe}:26,\mathrm{Co}:27,\mathrm{Ni}:28,\mathrm{Cu}:29,\mathrm{Zn}:30$$)
