Toppr Admin · Accepted Answer

The stability of -1 oxidation state among Al- Ga- In and Tl increases in the sequence-Al-lt-Ga-lt-In-lt-Tl-This is due to inert pair effect due to which- on moving down the group- the stability of -3 oxidation state decreases while-xA0-the stability of -1 oxidation state increases-

The stability of +1 oxidation state among Al, Ga, In and Tl increases in the sequence:Tl<In<Ga<AlGa<In<Al<TlIn<Tl<Ga<AlAl<Ga<In<Tl

The stability of +1 oxidation state among Al, Ga, In and Tl increases in the sequence.Al<Ga<In<Tl.This is due to inert pair effect due to which, on moving down the group, the stability of +3 oxidation state decreases while the stability of +1 oxidation state increases.

The stability of $+ 1$ oxidation state among $A l$ , $G a$ , $I n$ and $T l$ increases in the sequence:
$T l < I n < G a < A l$
$G a < I n < A l < T l$
$I n < T l < G a < A l$
$A l < G a < I n < T l$
