Nitrogen gas reacts with metal A at room temperature to form white solid B. B on reaction with pungent smell of gas C along with the formation of D. D is used as antacid. C reacts with HCl to give white precipitate of E. Find A to E and write balanced chemical equations.

Two different organic compounds A and B have the same molecular formula of C_2H_6O .A reacts with metallic sodium,to produce hydrogen gas but B does not react with metallic sodium. Write structural formulas of the compounds,A and B. Write the balanced chemical equation of the reaction of A. with metallic,sodium.

An element A occupies group number 15 and period number 3, exhibits allotropy and it is tetra atomic. A reacts with caustic soda a to give B which is having rotten fish odour. A reacts with chlorine to give C which has a smell of garlic. Identity A, B and C. Write the reactions.

Analysis of 30g of a compound D was found to contain 10g off element A and 20g of element B. again analysis of 45g of another compound E was found to contain 15g of element B and 30g of element C. caculate the amounts of D and E formed if 15g of A, 60g of B and 15g of C are mixed together and allowed to react with each other. also calculate total mass of the mixture after completion of the reaction. assume that no other reaction is possible except the reaction of B with A and C separately. state which laws of the chemical combination can be utilised in the calculation.

An organic compound [A], whose molecular formula is C_(3)H_(6)O , gives iodoform reaction and forms compound [B]. Compound [B], when heated with silver powder, converts into compound [C}. Compound [C] reacts with dil. Sulphuric acid and mercuric sulphate to obtain compound [D], which gives Aldol condensation reaction. Write down the names of all compounds from [A] to [D] and also write the chemical equations for each step.

An organic compound A(C_2H_6O) reacts with sodium to form compound B and hydrogen gas. When heated with conc. H_2SO_4 at 413 K, A produces C(C_4H_(10)O) . C on reaction with conc. HI at 373 K forms D. C is also obtained when B is heated with D. Identify A, B, C and D and write chemical equations for the formation of B from A and the formation of C from B and D.

A white solid (A) when heated liberates a colourless gas which does not support combustion. The residue is dissolved in water to form (B) which can be used for whitewashing. When excess of CO_2 gas is passed through the solution of (B), it gives a compound {C) which on heating forms (A). Identify (A), (B) and (C). Give the reactions.

An element A belongs to 14th group and occupies period number 6. A reacts with conc. HCl to give B an acid. A is used to prepare C which is used as an antiknock in automobilies. Identify the element A and the compounds B and C write the reactions

An organic compound A (C_3H_5N) when heated with concentrated NaOH, NH_3 gas evolved with formation of a sodium salt of carborylic acid (B). On reduction A give C(C_3H_9N)C when treated with Nitrous acid gives D. Find A,B,C,D and writes the relevant reactiosn involved.

When a brown compound of manganese (A) is treated with HCl it gives a gas (B). The gas taken in excess, reacts with NH_(3) to give an explosive compound (C ). Identify compounds A, B and C.
