A compound is treated with NaNH_(2) to give sodium salt. Identify the compound-

An organic compound 'A' is oxidized with Na_(2)O_(2) followed by boiling with HNO_(3) . The resultant solution is then treated with ammonium molybdate to yield a yellow precipitate. Based on above observation,the element present in the given compound is :

Qualitative analysis of organic compounds is performed by Lassaigne's test by fusion with metallic sodium, by which the covalent compounds are converted into ionic compounds. Extra elementsline N,S,P andhalogensaredetected by their usual tests. Q. Yellow precipitate in the detection of phosphorous when an organic compound is heated with Na_2O_2 and then boiled with conc. HNO_3 followed by the addition of ammonium molybdate is duw to the formation of :

The sodium extract of an organic compound on acidified with acetic acid and addition of lead acetate solution gives a back precipitate. The organic compound contains :

Two moles of organic compounds 'A' on treatment with a strong base gives two compounds 'B' and 'C'. Compound 'B' on dehydrogention with Cu gives 'A' while acidification of 'C' yields carboxylic and 'D' with molecular formula of CH_(2)O_(2) . Identify the compound A, B, C, and D.
