1.	In some of the reactions, thallium resembles aluminium whereas in others it resembles with group `1` metals. Support this statement by giving some evidence.
Answer» Aluminium (Al) generally exhibits +3 oxidation state in its compoudns. Thallium (Tl) the last member of the group -13, is expected to show oxidation states of +3 and +1 (due to inert pair effect). Thus, the metal resembles aluminium in exhibiting +3 oxidation state. Both form trichlorides `TiCl_(3)` and `AlCl_(3)` at the same time., it also resembles alkali metals of group 1 in exhibing +1 oxidation state (e.g., both thallium and sodium form monochlorides TiCL and NaCl) For further details, consult 11.2.

The heavier elements of groups 13 and 14 besides the group oxidation state exhibit another oxidation state which is two units lower than the group oxidation state and the stability of this lower oxidation state increases down the group. This concept which is commonly called inert pair effect has been used to explain many physical and chemical properties of the element of these groups.
