Question

Give below are two statements: One is labelled as Assertion $A$ and the other is labelled as Reason R: Assertion A: The stability order of +1 oxidation state of Ga, In and T1 is $Ga < In <$ T1. Reason R: The inert pair effect stabilizes the lower oxidation state down the group. In the light of the above statements, choose the correct answer from the options given below:

Options:

Answer:

C

Solution:

The relative stability of +1 oxidation state progressively increases for heavier elements due to inert pair effect. $∴$ Stability of $A ℓ^{+ 1} < Ga^{+ 1} < In^{+ 1} < T ℓ^{+ 1}$

The relative stability of +1 oxidation state progressively increases for heavier elements due to inert pair effect. ∴ Stability of A ℓ + 1 < Ga + 1 < In + 1 < T ℓ + 1
