Write the structures and IUPAC names of the compounds with molecular formula, C_(4)H_(8)O_(2) .

An aromatic compound of molecular formula C_8H_(10) reacts with a mixture of concentrated HNO_3 and concentrated H_2SO_4 to form a mononitro compound. The structural formula of C_8H_(10) is

Primary alkyl halide C_(4)H_(9)Br (A) reacted with alcoholic KOH to give compound (B). Compound (B) is reacted with HBr to give (C) which is an isomer of (A). When (A) is reacted with sodium metal it gives compound (D), C_(8)H_(18) which is different from the compound formed when n-butyl bromide is reacted with sodium. Give the structural formula of (A) and write the equations for all the reactions.

The number of isomers of a benzenoid aromatic compound having molecular formula, C_(7)H_(8)O is _______

An organic compound (A) with molecular formula C_(8)H_(8)O forms an orange-red precipitate with 2,4-DNP reagent and gives yellow precipitate on heating with iodine in the presence of sodium hydroxide. It neither reduces Tollens or Fehlings reagent, nor does it decolourise bromine water or Baeyerâs reagent. On drastic oxidation with chromic acid, it gives a carboxylic acid (B) having molecular formula C_(7)H_(6)O_(2) . Identify the compounds (A) and (B) and explain the reactions involved.

An organic compound 'A' (C_2H_6O) reacts with sodium to form a compound 'B' with the evolution of hydrogen gas and gives a yellow compound 'C' when treated with iodine and NaOH. When heated with conc. H_2SO_4 at 140^@C it gives a compound 'D' C_4H_(10) which on treatment with HI at 100^@C gives 'E'. 'B' when heated with 'E' also gives back 'D'. Identify 'A' to 'E' and write equations for the reaction involved.
