Question

The stability of +1 oxidation state among textAl, Ga, In and textTl increases in the sequence: (A) Ga < In < Al < Tl (B) Al < Ga < In < Tl (C) Tl < In < Ga < A (D) In < Tl < Ga < Al

Tardigrade Admin · Accepted Answer

Stability of +1 oxidation state due to inert pair effect is in the order Al < Ga < In < Tl

Q. The stability of +1 oxidation state among $Al, Ga, In$ and $Tl$ increases in the sequence:

$G a < I n < A l < Tl$

$A l < G a < I n < Tl$

$Tl < I n < G a < A$

$I n < Tl < G a < A l$

Stability of +1 oxidation state due to inert pair effect is in the order $A l < G a < I n < Tl$

Q. The stability of +1 oxidation state among Al, Ga, In and Tl increases in the sequence:

Ga<In<Al<Tl

Al<Ga<In<Tl

Tl<In<Ga<A

In<Tl<Ga<Al
