JEE MAIN 2024
08.04.24_(S1)
Question
Given 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 Tl is Ga 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 :
Select the correct option:
A
Both A and R are true and R is the correct explanation of A.
B
A is true but R is false.
C
Both A and R are true but R is NOT the correct explanation of A.
D
A is false but R is true.
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
The relative stability of +1 oxidation state progressively increases for heavier elements due to inert pair effect. ∴ Stability of $\mathrm{A} \ell^{+1}<\mathrm{Ga}^{+1}<\mathrm{In}^{+1}<\mathrm{T} \ell^{+1}$
