Which of the following compounds undergo disproportionation in aqueous

1.	Which of the following compounds undergo disproportionation in aqueoussolution ?
Answer» `TlCl_(3)` `GaCl` `InCl` `TlCl` Solution :The MAXIMUM O.S. of TL is `+3`, therefore, Tl in `TlCl_(3)` cannot increases its O.S. beyond +3. Further, since +1 O.S. of Tl is muchmore STABLE than +3, therefore, Tl in `TlCl` is not LIKELY to INCREASE its O.S. to +3 . Thus, both `TlCl_(3)`and `TlCl`do not undergodisproportionation. Thus. options (b) and (c ) not correct.
