Answer» Solution :Isomer (i) gives white ppt. of `BaSO_(4)` with `BaCl_(2)` whereas isomer (ii) does not form àppt. At the same TIME isomer (ii) gives a yellow precipitate of silver bromide with AGNO, but (i) does not. (b) The water molecule in isomer (ii) is lost. EASILY on heating whereas the water molecules in isomer (i) are not lost easily, being coordinated to the CENTRAL atom. (C) (i) Optical (ii) Geometrical (iii) Geometrical (d) (a-p,s)(6-,R)(C-9.), (d-p,s)
