The \(E^{\ominus}\) values for
\(\begin{aligned} & \mathrm{Al}^+ / \mathrm{Al}=+0.55 \mathrm{~V} \text { and } \mathrm{Tl}^{+} / \mathrm{Tl}=-0.34 \mathrm{~V} \\ & \mathrm{Al}^{3+} / \mathrm{Al}=-1.66 \mathrm{~V} \text { and } \mathrm{Tl}^{3+} / \mathrm{Tl}=+1.26 \mathrm{~V} \end{aligned} \)
The incorrect statement among the following is:
1. Al is more electropositive than TI
2. Tl3+ is a good reducing agent than Tl1+
3. Al+ is unstable in solution.
4. Tl can be easily oxidized to Tl+ as compared to Tl3+
