A synthesis of 2,5 - dimethyl- 2 -hexanol from 2 - methylpropene requires the for mation of two four carbon intermediates, X and Y. These intermediates combine to give the desired product after the usual hydrolysis work-up. Select the appropriate methods of preparing X and Y from 2-methylpropene.
  • a)
    X add HBr, then react with Mg in ether Y add water, acid-catalysis
  • b)
    X add HBr (peroxides), then react with Mg in ether Y react with C6H5CO3H in CH2CI2
  • c)
    X add HOBr Y add B2H6 in ether, then NaOH
  • d)
    X add HOBr Y add HBr (peroxides), then react with Mg in ether
Correct answer is option 'B'. Can you explain this answer?

Explanation:

c) X add HOBr Y add B2H6 in ether, then NaOH
This method involves the addition of HOBr to 2-methylpropene to form an intermediate X, followed by the addition of B2H6 in ether and then NaOH to form the desired product. However, this method is not suitable for the synthesis of 2,5-dimethyl-2-hexanol.

d) X add HOBr Y add HBr (peroxides), then react with Mg in ether
This method involves the addition of HOBr to 2-methylpropene to form an intermediate X, followed by the addition of HBr (peroxides) to form intermediate Y, which then reacts with Mg in ether to give the desired product. This method does not lead to the formation of the required intermediates X and Y for the synthesis of 2,5-dimethyl-2-hexanol.

b) X add HBr(peroxides), then react with Mg in ether Y react with C6H5CO3H in CH2Cl2
This method involves the addition of HBr (peroxides) to 2-methylpropene to form intermediate X, which then reacts with Mg in ether to give intermediate Y. Intermediate Y is further reacted with C6H5CO3H in CH2Cl2 to yield the desired product, 2,5-dimethyl-2-hexanol. This method is the appropriate one for preparing intermediates X and Y required for the synthesis of 2,5-dimethyl-2-hexanol.

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
