Stability of monovalent and trivalent cations of Ga. In lie the following sequence

Answer»

`Ga^(3+) LT In^(3+) gt TL^(3+)`
`Ga^(3+) gt In^(3+) gt Tl^(3+)`
`Tl^(o+) gt In^(o+) gt Ga^(o+)`
`Ga^(o+) gt "In"^(o+) gt Tl^(o+)`

Solution :`{:(Ga^(+3)gtIn^(+3)gt Tl^(+3)),(Tl^(+)gt In^(+) gtGa^(+)):}}`DUE to inert pair effect
