(1) ${\mathrm{Al}}^{+}$is unstable in solution because $\mathrm{SRP}$ of ${\mathrm{Al}}^{+}/\mathrm{Al}$ is positive hence, it will get reduced in solution. (2) $\begin{array}{ll}\mathrm{Tl}/{\mathrm{Tl}}^{+}=+0.34& (\mathrm{SOP})\\ \mathrm{Tl}/{\mathrm{Tl}}^{3+}=-1.26& (\mathrm{SOP})\end{array}$ Since, SOP TI/TI $>$ TI/T1 ${}^{+}$ Hence, $\mathrm{TI}$ will get oxidised to ${\mathrm{Tl}}^{+}$easily than ${\mathrm{Tl}}^{3+}$ (3) Since ${\mathrm{Al}}^2/{\mathrm{Al}}^{3+}$ has more SOP than $\mathrm{Tl}/{\mathrm{Tl}}^{+}$it will be more electropositive (4) Since $\begin{array}{r}{\mathrm{Tl}}^{3+}+2{\mathrm{e}}^{-}\to {\mathrm{Tl}}^{+};\mathrm{E}=\frac{3\times 1.26+0.34}{2}\\ =+2.04\end{array}$ Hence, ${\mathrm{Tl}}^{3+}$ is better oxidising agent not reducing agent
