MCQ
The possible oxidation state of $Tl$ are
- A$+1$ and $+2$
- B$+2$ and $+3$
- C$+1$ and $-1$
- ✓$+1$ and $+3$
✓
Answer
Correct option: D.
$+1$ and $+3$
d
Tl shows both +1 and +3 oxidation states. The stability of +1 oxidation state increases down the group $\mathrm{T} 1>\mathrm{In}>\mathrm{Ga}>\mathrm{Al}$ and +3 oxidation state is highly oxidising in character.
