Group 13 elements show +1 and +3 oxidation states. Relative stability of +3 oxidation state may be given as
A
T13+>In3+>Ga3+>Al3+>B3+
B
B3+>Al3+>Ga3+>In3+>Tl3+
C
Al3+>Ga3+>Tl3+>In3+>B3+
D
Al3+>B3+>Ga3+>Tl3+>In3+
Answer
B3+>Al3+>Ga3+>In3+>Tl3+
Explanation
Solution
: Stability of + 3 oxidation state decreases from Al to Tl. B always shows +3 oxidation state in all of its compounds.
