13th group elements show +1 and +3 oxidation states. 14th group elements show +2 and +4 oxidation states. Correct order about the stability of their oxidation states is
detailed solution
Correct option is A
In 13th group, stability of +3> +1 …except in Thallium ;In 14th group stability of +4>+2….except in Lead ;Thallium due to inert pair effect is more stable in “+1” state;Tl and Pb show inert pair effect. They are stable in their lower oxidation state;Other than Tl and Pb remaining elements are stable in their group number oxidation state ;Similar Questions
