A metallic element A bums In nitrogen gas to form an ionic compound ‘B’ which on treatment with water forms ‘C’ and ‘D’ solution of ‘C’ turns milky on bubbling `CO_2` gas through it:- Give equations for the formation of C and D from B.

Element A burns, in nitrogen to give an ionic compound B. The compound B reacts with 'H2O' to give 'C' and 'D'. A solution of 'C' becomes milky on bubbling 'CO2'. Identify 'A, B, C, D'.

Benzamide (C_6H_5CONH_2) on heating with bromine and NaOH gave a compound A which is soluble in dilute acid. When A is warmed with chloroform and alc KOH, B is formed which has an unpleasant odour. Using chemical equation represent the formation of B from A.

A, white powder (A) whén heated gave off a coloúrless gas (B) which turns the lime water milky. The residue (C) was yellow when hot but turned white on cooling. Identify '(A),(B)' and '(C)' Write the equation for the action of heat on (B).

Form the differential equation corresponding to y=a x^2+b x+c

A compound A (CH_4O) on treatment with KCN gives a compound B (C_2 H_3N) which is acyanide.The compound ‘B’on partial hydrolysis gives C (C_2H_5ON) which is a neutral compound. ‘C’ on treatment with Br_2 and NaOH gives D (CH_5N) which turns red litmus blue. ‘D’ on reaction with nitrous acid gives back ‘A’. Name the conversion of ‘C’ into 'D'.

An aromatic compound on treatment with aqueous ammonia and heating forms compound 'B' which on heating with 'Br_2' and 'KOH' forms a còmpound of molecular formula 'C6 H7N'. Write the structures and IUPAC names of compounds 'A, B' and 'C'.

An organic compound 'A' on reduction gives compound 'B' which on reaction with trichloromethane and caustic potash forms 'C'. The compound 'C' on catalytic reduction gives N-methylbenzenamine, the compound 'A'is

The aqueous solution of a nitrogen and chlorine containing organic compound (A) is acidic to litmus. (A) on treatment with aqueous NaOH, it gives a compound (B) containing nitrogen, but not chlorine. Compound (B) on treatment with C_6 H_5SO_2 Cl in the presence of NaOH gives an insoluble product (C) C13H13NO2 S. Give the structures of (A) and (B).

Compound (A) 'C_6 H_12 O_2' an reduction with LiAl H_4 yielded two compounds (B) and (C) . The compound (B) on oxidation gave (D) which on treatment with alkali aqueous and subsequent heating furnished (E). The latter on catalytic hydrogenation gave (C). The compound (D) was oxidised further to give (F) which was found to be monobasic acid (m. wt. 60). Deduce structures of A to (E).
