Reactions of compound J (C₉H₈O₂) indicates that it has C = C linkage and – COOH group. Thus, J can be written as C₆H₅CH = CH COOH. Since, J is unsaturated carboxylic acid and it is formed by the reactions of compound I with (CH₃CO)₂O and CH₃COONa, compound I should be an aldehyde (recall Perkin reaction). Thus the whole series of reactions can be written as below.

Passage IA and B are two structural isomers with their molecular formula C7H14Oand both gives-off effervescence on heating with Na-metal. However, neither A nor B decolourise brown colour of Br2-H2O. Treating either A or Bwith hot conc, sulphuric acid solution results in the form ation of the same compound C (C7H12). C on treatment with O3 followed by Zn-H2Ogives D (C7H12O2). D gives E (C7H16O2) on treatm ent with NaBH4. E has only one methyl group and forms yellow ppt with I2/KOH. Also, A gives delayed turbidity on treatment with conc. HCI/ZnCI2 while B gives immediate turbidity on similar treatment.Q.Which of the following statement regarding A and B is incorrect?

Both the Cβ–H and Cα–X bonds are breaking in the transition state of E2 reactions. The rate of E2 reaction is of second order. The rate shows primary isotopic (deuterium) effect, i.e. if Cβ–H is replaced by Cβ–D, the rate of reaction decreases sharply. The rate is also corelated with nucleofugality i.e. the ability of leaving group to leave. With a better nucleofuge, the rate of reaction increases. This is called the element effect.The element effect is also observed in E1cB reactions in which the second step is rate determining and elimination of first order w.r.t. conjugate base is observed. For E1cB reaction KH/KD ~ 1, therefore proton abstraction is not involved in the rate determing step. In D2O the incorporation of Deuterium at Cβ–H in the substrate is found many times faster than rate of elimination, in E1cB reaction.In E1 reaction only nucleofuge departs in slow step and a carbocation intermediate is formed.Q.For the given compounds I and II the rate of elimination byWhat is true about this reaction

An organic compound A (C8H4O3)in dry benzene in the presence of anhydrous aluminium chloride gives compound B. The compound B on treatment with PCl5 followed by reaction with (H2/PdBaSO4)gives compound C which on treatment with hydrazine gives a heterocyclic compound D. When compound A is heated with phenol in presence of an acid, an acid base indicator (E) is formed. Identify the compounds A to E.?
