Passage II
An organic compound A(C9H10O) is chiral and does not evolve any gas on treatment with Na-metal but on hydrolysis with dil. H2SO4 gives B (C9H12O2) which on further treatment with alkaline solution of iodine does not give an yellow precipitate. Also A on treatment with excess of conc. HBr gives C (C9H11OBr) as the major product. C on further treatment with C2H5ONa/C2H5OH followed by acidification of product gives D (an isomer of A). D on ozonolysis followed by work-up with dimethyl sulphide gives E (C8H8O2) as one of the product.
Q. 
Which of the following statement regarding B is correct?
  • a)
    B is an optically inactive substance
  • b)
    B is an optically active substance with same configuration as that of A
  • c)
    B is an optically active substance with opposite configuration to that of A
  • d)
    A pure enantiomer of A will produce, on hydrolysis reaction, a racemic mixture of B
Correct answer is option 'B'. Can you explain this answer?

Consider a solution of CH3COONH4 which is a salt of weak acid weak base. Theequilibrium involved in the solutions are :If we add these three reactions, then the net reaction isBoth CH3C00- and NH4 get hydrolysed independently and their hydrolysis depends on(i) their initial concentration(ii) the value of Kh which is Since both of the ions were produced from the same salt, their initial concentrations are same . Therefore unless untial the value of Kw/Kaand Kb is same, the degree of hydrolysis of ion cant be same.To explain why we assume that degree of hydrolysis of cation and anion is same, we need to now look at the third reaction i.e., combination of H+ and OH ions. It is obvious that this reaction happens only because one reaction produced H+ ion and the other produced OH ions. We can also note that this reaction causes both the hydrolysis reaction to occur more since their product ions are being consumed. Keep this thing in mind that the equilibrium which has smaller value of equilibrium conxtant is affected more by the common ion effect. For the same reason if for any reason a reaction is made to occur to a greater extent by the consumption of any one of the product ion, the reaction with the smaller value of equilibrium constant tends to get affected more.Therefore we conclude that firstly the hydrolysis of both the ions ocurs more in the presence of each other (due to consumption of the product ions) than in each other is absence. Secondly the hydrolysis of the ion which occurs to a lesser extent (due to smaller value of Kh) is affected more than the one whose Kh is greater. Hence we can see that the degree of hydrolysis of both the ions would be close to each other when they are getting hydrolysed in the presence of each other.Q.In a solution of NaHCO3 , the amphiprotic anion can under ionization to form H+ ion and hydrolysis to from OH ion.To calculat PH, suitable approximation is
