Read the given information and answer the following questions. A survey was conducted in two villages, Vanaparthy and Vaddicherla of Warangal district in Telangana State. The first with no scarcity and the second with scarce groundwater. Well census was carried out in the villages in order to get a complete picture of well irrigation and its status as well as availability of water. There are no alternative sources of supply as against wells in Vaddicherla, where there is an existing tank that has been converted into a percolation tank, so that the water situation is much better in Vanaparthy. In which village, do you suggest drip irrigation ?

A compound (A) is greenish crystalline salt, which gave the following results. i) Addition of BaCl_(2) solution to the solution of (A) results in the formation of white ppt. (B). which is insoluble in dil HCL ii) On heating (A), water vapours and two oxides of sulphur, (C) and (D) are liberated leaving a red brown residue (E) iii) (E) dissolves in warm conc. HCI to give a yellow solution (F). iv) With HS the solution (F) yields a pale yellow ppt. (G) which when filtered, leaves a greenish filtrate (H). v) Solution (F) on treatment with thiocynaate ions gives blood red coloured compound (I). The yellow solution is of

Complex compounds are molecular compounds which retain their indentities even when dissolved in water. They do not give all the simple ions in solution but instead furnish complex ions. The complex compounds are often called coordination compounds because certain groups called ligands are attached to the central metal ion by coordinate or dative bonds. Coordination compounds exhibit isomerism, both structural and stereoisomerism. The struculre, magnetic property, colour and electrical properties of complexes are explained by various theories. which of the following pairs, both the complexes have the same geometry?
