Group 13 elements show +1 and +3 oxidation states. Relative statibility of +3 oxidation may be given as

A

`Ti^(3+)gtIn^(3+)gtGa^(3+)gtAl^(3+)gtB^(3+)`

B

`B^(3+)gtAl^(3+)gtGa^(3+)gtIn^(3+)gtTi^(3+)`

C

`Al^(3+)gtGa^(3+)gtIn^(3+)gtB^(3+)`

D

`Al^(3+)gtB^(3+)gtGa^(3+)Ti^(3+)gtIn^(3+)`

Text Solution

Verified by Experts

Stability of +3 oxidation state decreases down the group because of inerg pair effect. Therefore, it is the correct sequence
