Passage-I : Metallic sulphates can be obtained by reacting the metals (above hydrogen in ECS), or its oxide, hydroxide or carbonate with dil. H_(2)SO_(4) . Group IA metals also form hydrogen sulphates which can be isolated in solid. In general metal sulphates are soluble in water and crystallize with water of crystallization. Sulphates are thermally more stable than nitrates. Select the thermally more stable salt from given pairs: A) Al_(2)(SO_(4))_(3)" "B)Al(NO_(3))_(3)" "C) Ca(NO_(3))_(2)" "D) CaSO_(4)" "E )FeSO_(4)" "F) Fe(NO_(3))_(2)

Olefins can be halogenated in the allylic position by number of reagents of which N-bromo succinimide (NBS) is the most common. When this reagent is used the reaction is known as WohlZiegler bromination. Other N-bromoamides have also been used. To a much lesser extent allylic chlorination has been carried out with N-chloro-succinimide. N-Chloro-N-cyclohexyl benzene sulphonamide or t-hypochlorite when the allylic radical intermediate is unsymmetrical allylic rearrangement takes place so that the mixture of both possible products is obtained. CH_3 - CH_2 -CH = CH_2underset(hv)overset(NBS)(to) CH_3 - CH = CH - CH_2 - Br + CH_3 - undersetoverset(|)(Br)(C ) - CH = CH_2 NBS is also a highly regioselective brominating agent at other positions, including positions a to a carbonyl group. Which of the following is allylic chlorinating agent ?
