A white 'A' on heating decomposes to produce two products 'B' and 'C'. 'B' on reaction with white phosphorous produces 'D', which is a strong dehydrating agent. 'D' on reaction with perchloric acid converts it to its anhydride.
The compound 'A' is:

A white 'A' on heating decomposes to produce two products 'B' and 'C'. 'B' on reaction with white phosphorous produces 'D', which is a strong dehydrating agent. 'D' on reaction with perchloric acid converts it to its anhydride. The product obtained on hydrolysis (complete) of D is:

A white 'A' on heating decomposes to produce two products 'B' and 'C'. 'B' on reaction with white phosphorous produces 'D', which is a strong dehydrating agent. 'D' on reaction with perchloric acid converts it to its anhydride. The number of moles of H_(2)O needed to hydrolyse (complete) 1 mole of D is:

A colourless inorganic compound (P) decomposes on heating to give two products (Q) and (R). (Q) is a colourless neutral gas with a sweet odour which when burnt with phosphorous produces a strong dehydrating agent (S) while (R) is a neutral liquid at room temperature. Identify P, Q, Rand S.

Two moles of organic compound 'A' on teratment with a strong base give two compounds 'B' and 'C'. Compound 'B' on dehydrogenation with Cu gives 'A' while acidification of 'C' yield carboxylic acid 'D' with molecular formula of CH_2O_2 . Identify the compounds A, B, C and D. Write all chemical reactions involved.

A colourless inorganic salt (A) decomposes completely at about 25^(@)C to give only two products, (B) and (C ), leaving no residue. The product (C ) is a liquid at room temperature and neutral to moist litmus paper while the gas (B) is a neutral oxide. White phosphorus burns in excess of (B) to produce a strong white dehydrating agent. Write balanced equations for the reactions involved in the above process.

An organic compound [A] is C_(5)H_(8)O_(3). On heating with soda lime, it gives [B]. The compound [B] reacts with HCN to give another compound [C] which reacts with thionyl chloride to produce [D]. When the compound [A] is heated with potassium dichromate the product is acetic acid and malonic acid. The compound [A] is a
