1.	An inorganic compound (A) shows the following reactions. It is white solid and exits as dimer(i) gives fumes of (B) with much wet air(ii) It sublimes on 180^(@)C turns forms monomer if heated to 400^(@)C(iii) Its aqueous solution turns blue litmus to red(iv) Adition of NH_(4)OH and NaOH seperately to a solution of (A) gives white precipitate which is however soluble in excess of NaOHB may be
Answer» `AlCl_3` `Al_(2)Cl_(6(s))` `AlF_3` `Al_(2) F_6` SOLUTION :(A) is a characteristics DIMERIC compound which sublimes on `180^@C` and FORM monmer if heated to `400^@C` and THUS (A) is `(AlCl_3)` or `Al_(2)Cl_(6)` `Al_(2)Cl_(6(s))overset(180^@C) rarr Al_(2)Cl_(6(v)) rarr overset(400^@C) rarr 2AlCl_3`
