Question

The $\mathrm{E}^{\Theta}$ values for

$$\begin{aligned} & \mathrm{Al}^{+} / \mathrm{Al}=+0.55 \mathrm{~V} \text { and } \mathrm{Tl}^{+} / \mathrm{Tl}=-0.34 \mathrm{~V} \\ & \mathrm{Al}^{3+} / \mathrm{Al}=-1.66 \mathrm{~V} \text { and } \mathrm{T}^{3+} / \mathrm{Tl}=+1.26 \mathrm{~V} \end{aligned}$$

Identify the incorrect statement

$\mathrm{Al}$ is more electropositive than $\mathrm{Tl}$

$\mathrm{Tl}^{3+}$ is a good reducing agent than $\mathrm{Tl}^{1+}$

$\mathrm{Al}^{+}$ is unstable in solution

$\mathrm{Tl}$ can be easily oxidised to $\mathrm{Tl}^{+}$ than $\mathrm{Tl}^{3+}$
