The stability of `+1` oxidation state increases in the sequence :

A

`Tl lt" In "lt Ga lt Al`

B

`"In "lt Tl lt Ga lt Al`

C

`Ga lt" In "lt Al lt Tl`

D

`Al lt Ga lt" In "lt Tl`

Text Solution

Verified by Experts

The correct Answer is:
D
Due to the inert pair effect, group 13 elements show +1 oxidation state also besides the group Oxidation state +3, and the stability of lower oxidation state, i.e. +1, increases down the group `(darr)`.
