CHXI11:THE P-BLOCK ELEMENTS
316485
Thallium shows +1 oxidation state in its stable compounds because
1 Of its high reactivity
2 Of inert pair effect
3 Of its amphoteric nature
4 It is a transition metal
Explanation:
Due to inert pair effect, \(\mathrm{Tl}\) shows +1 oxidation state.

Read the Statement - A and Statement - B carefully to mark the correct options given below Statement A : In group 13, the stability +1 oxidation state increases down the group. Statement B : The atomic size of gallium is greater than that of aluminium.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Due to inert pair effect, stability of +1 oxidation state increases down the group 13 elements. The atomic size of aluminium is greater than that of gallium \({\mathrm{\mathrm{(\mathrm{Tl}>\mathrm{In}>\mathrm{Al}>\mathrm{Ga}>\mathrm{B})}}}\) \({\rm{Atomic \,radius}}\,{\rm{(pm):}}\mathop {{\rm{Tl}}}\limits_{{\rm{(107)}}} {\rm{ > }}\mathop {{\rm{In}}}\limits_{{\rm{(167)}}} {\rm{ > }}\mathop {{\rm{Al}}}\limits_{{\rm{(143)}}} {\rm{ > }}\mathop {{\rm{Ga}}}\limits_{{\rm{(135)}}} {\rm{ > }}\mathop {\rm{B}}\limits_{{\rm{(88)}}} \) So, the correct option is (1)

Aluminium is usually found in +3 oxidation state.In contrast, thallium exists in +1 and +3 oxidation states. This is due to
1 Lattice effect
2 Lanthanoid contraction
3 Inert pair effect
4 Diagonal relationship.
Explanation:
Due to inert pair effect, last elements of Gr. 13, 14, 15 show lower oxidation state. Ex: \({\text{Tl + 1,}}\quad {\text{Pb + 2,}}\quad {\text{Bi + 3}}{\text{.}}\)

1 \(\mathrm{B}\)
2 \(\mathrm{Al}\)
3 \(\mathrm{Ga}\)
4 \(\mathrm{Tl}\)
Explanation:
Due to high electronegativity, boron exhibits -ve oxidation state.
