An organic compound containing C,H and O has molecular mass 86. It does not reduce Tollen’s reagent but gives iodoform test. On vigorous oxidation it gives mixture of acetic acid and propionic acid. Write the possible structure of the compound giving explanations.

An organic compound of molecular formula C_3H_6 O did not give a silver mirror with Tollen 's reagent but gave an oxime with hydroxyl amine, it may be

An organic compound C_(8)H_(18) on monochlorination gives a single monochloride. Write the structure of the hydrocarbon.

An organic compound A(C_(5)H_(8)O_(3)) on heating with soda lime gives B which reacts with HCN to give C. The compound C reacts with thionyl chloride to produce D which on reaction with KCN gives a coompound E. Alkaline hydrolysis of E gives a salt F which on heating with soda lime produces n-butane. Careful oxidation of A with dichromate gives acetic acid and malonic acid. Give the structures from A to F with proper reason.

An organic compound gives hydrogen on reacting with sodium metal. It also gives iodoform test and forms an aldehyde of molecular formula C_(2)H_(4)O on oxidation with acidified dichromate. Name the compound and give the equation of these reactions.

An organic compound (A) with molecular formula C_8H_8O forms an orange precipitate with 2, 4 dinitrophenyl hydrazine and gives yellow precipitate on heating with iodine in presence of sodium hydroxide. It neither reduces Tollen's reagent nor Fehling solution and it also does not decolourise bromine water or Baeyer's reagent. On drastic oxidation with chromic acid it gives a carboxylic acid (B) having molecular formula C_7H_6O_2 . Identify the compound (A) and (B) and explain in detail the reactions involved

An organic compound (P) having molecular formula C_(9)H_(10)O form an orange precipitate (Q) with 2,4-DNP reagent. Compound (P) gives a yellow precipitate (R ) when heated in the presence of iodine and NaOH along with a colourless compound (S). (P) neither reduce Tollen's reagent or Fehling's solution nor it decolourises bromine water. On drastic oxidation of (P) with chromic acid, a carboxylic acid (T) having molecular formula C_(7)H_(6)O_(2) is obtained. Deduce the structures of the compounds (P) to (T).

A compound with MF-C_3H_6O gives+ve iodoform test. Name the compound.
