Vedclass · Answer

(D) The group oxidation state for group $13$ elements is $+3$. As we move down the group,the stability of the $+1$ oxidation state increases due to the inert pair effect. Thallium $(Tl)$ shows both $+1$ and $+3$ oxidation states,but the $+1$ state is more stable than the $+3$ state. However,the question asks for the element that does not show the group oxidation state $(+3)$. Actually,all elements in group $13$ can show $+3$ oxidation state,but for Thallium,the $+1$ state is significantly more stable,and it often exists in the $+1$ state in its compounds,making the $+3$ state less characteristic compared to others. Therefore,Thallium is the correct answer as it shows a strong preference for the $+1$ oxidation state.

Which element of the $13^{th}$ group does not show the group oxidation state in its compounds?
