Some properties of Sulphuric acid are listed below . Choose the property a,b,c and d which is responsible for the reaction (i) to (v) . Some properties my be repeated : (a) Acid (b) Deydrating agent (c ) Non - volatile acid (d) Oxidising agent. NaCl + H_(2)SO_(4) to NaHSO_(4) + HCl

100% yield of picric acid is not obtained by nitration of phenol as some of the phenol is oxidised to (A) Benzaldehyde (B) Benzoic acid (C) Benzena - 1 2- diol (D) p - benzoquinone

A, B, C and D illustrate the properties of sulphuric acid whether dilute or concentrated.Choose the role played by sulphuric acid as A, B, C, or D which is responsible for the reaction. Some role(s) may be repeated. Zn + 2H_2SO_4(conc.) to ZnSO_4 + SO_2 + 2H_2O A : Dilute acid B : Dehydrating agent C : Non - volatile acid D : Oxidising agent
