1. \[\ce{RCN ->[reduction]}\]
2. \[\ce{RCN ->[(i) CH3MgBr][(ii) H2O]}\]
3. \[\ce{RNC ->[hydrolysis]}\]
4. \[\ce{RNH2 ->[HNO2]}\]

You are given four organic compounds “A”, “B” , “C” and “D”. The compounds “A”, “B” and “C” form an orange-red precipitate with 2, 4 DNP reagent. Compounds “A” and “B” reduce Tollen’s reagent while compounds “C” and “D” do not. Both “B” and “C” give a yellow precipitate when heated with iodine in the presence of NaOH. Compound “D” gives brisk effervescence with sodium bicarbonate solution. Identify “A”, “B”, “C” and “D” given the number of carbon atoms in three of these carbon compounds is three while one has two carbon atoms. Give an explanation for our answer.

Which of the following compounds gives a positive Tollen's test but negative Fehling's test?

Oxidation of ketones involves carbon-carbon bond cleavage. Name the products formed on oxidation of 2, 5-dimethylhexan-3-one.

A and B are two functional isomers of compound C₃H₆O.On heating with NaOH and I₂, isomer B forms yellow precipitate of iodoform whereas isomer A does not form any precipitate. Write the formulae of A and B.

An organic compound 'A' with the molecular formula C₄H₈O₂ undergoes acid hydrolysis to form two compounds 'B' and 'C'. Oxidation of 'C' with acidified potassium permanganate also produces 'B'. Sodium salt of 'B' on heating with soda lime gives methane.

1. Identify 'A', 'B' and 'C'.
2. Out of 'B' and 'C', which will have higher boiling point? Give reason.

Which of the following compounds will give butanone on oxidation with alkaline \[\ce{KMnO4}\] solution?

Give a simple chemical test to distinguish between the following pair of compounds:

Ethanal and Propanal
