WORD PROBLEMS
An aromatic compound A on treatment with aqueous ammonia and heating forms compound B which on heating with Br2 and KOH forms compound C of molecular formula C6H7N .Write the structures and IUPAC names of compounds A,B,C.
2. An organic compound A with molecular formula C8H16O2 was hydrolysed with sulphuric acid to give a carboxylic acid B and alcohol C. Oxidation of C with chromic acid produced B. C on dehydration gives but-1-ene.Write reactions involved.
3. An organic compound A which has a characteristic odour on treatment with NaOH forms two compounds B and C. Compound B has a molecular formula C7H8O which on oxidation gives back compound A. Compound C is sodium salt of acid. C when heated with sodalime yields an aromatic hydrocarbon D. Deduce structures A-D .
4. A compound ‘X’ (C2H4O) on oxidation gives ‘Y’ (C2H4O2). ‘X’ undergoes haloform reaction. On treatment with HCN ‘X’ forms a product ‘Z’ which on hydrolysis gives 2- hydroxypropanoicacid. (i) Write down structures of ‘X’ and ‘Y’. (ii) Name the product when ‘X’ reacts with dilNaOH. (iii) Write down the equations for the reactions involved.
5. Primary alkyl halide C4H9Br (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), C8H18 which is different from the compound formed when n-butyl bromide is reacted with sodium. Give the structural formula of (a) and write the reactions for all.

It neither reduces Tollens’ or Fehlings’ reagent, nor does it decolourise bromine water or Baeyer’s reagent. On drastic oxidation with chromic acid, it gives a carboxylic acid (B) having molecular formula C7H6O2. Identify the compounds A and B and explain the reactions involved.
7. . An organic compound with the molecular formula C9H10O forms 2,4-DNP derivative, reduces Tollens’ reagent and undergoes Cannizzaro reaction. On vigorous oxidation, it gives 1,2- benzenedicarboxylic acid. Identify the compound
