JEE MAIN - Chemistry (2023 - 31st January Morning Shift - No. 5)
The correct order of basicity of oxides of vanadium is :
$$\mathrm{V_2O_3 > V_2O_5 > V_2O_4}$$
$$\mathrm{V_2O_3 > V_2O_4 > V_2O_5}$$
$$\mathrm{V_2O_5 > V_2O_4 > V_2O_3}$$
$$\mathrm{V_2O_4 > V_2O_3 > V_2O_5}$$
Explanation
$\mathrm{V}_{2} \mathrm{O}_{3}>\mathrm{V}_{2} \mathrm{O}_{4}>\mathrm{V}_{2} \mathrm{O}_{5}$
As positive oxidation state increases acidic nature increases and basic nature decreases.
As positive oxidation state increases acidic nature increases and basic nature decreases.
