For which of the following +3 oxidation state is highly oxidising in character?
Options
- AAl
- BGa
- CIn
- DTI
Correct answer
D. TI
Step-by-step solution
Among the given elements of group 13, Tl in +3 oxidation state is highly oxidising in nature. This is because on going down in the group the inert pair effect become more and more prominent. This causes the decrease in the stability of elements in +3 oxidation state and increase in +1 oxidation state.
