Question

4What is the minimum required mass of NaOH that would be required to completely convert 121 mL of methyl salicylate to salicylic acid? This question is not linked to the question above numerically. 5.Building on question 4, how many mL of 3M H2SO4 would be required to neutralize this solution? 6.0ne gram of salicylic acid dissolves in 460 mL of room temperature water, and in 15 mL of boiling water. What is the maximum percent recovery that can be achieved using water as a recrystallization solvent assuming the recrystallization mixture is not cooled below room temperature? 7.During the transformation of methyl salicylate into salicylic acid, all but one step is reversible. Which step in the reaction mechanism is irreversible? Indicate your answer using line bond structures. e 8.A student is given a solution of 20 ml of ether, which contains benzoic acid and benzocaine The student uses 5% NaOH to separate the benzoic acid from the benzocaine benzocaine is expected to remain in the organic layer (ether layer) After drying the organic The layer, and removing the diethyl ether using a rotavapor, the student finds no benzocaine in the RBF. The student performed the experiment exactly, and no equipment was did the benzocaine end up? HINT Use the malfunctioning mechanistic force to help explain!! Where он нN benzocaine I benzoic acid 9 Using arrows to indicate the flow of electrons, provide a step-by-step mechanism which outlines the following transformation. a) HaoH, HO b) H,O workp

Answer 1

Question 4.

The minimum mass of NaOH required = Same as the moles of methyl salicylate

= (1.21 mL * 1.17 g.mL^-1/152.1494 g.mol^-1) * 40 g/mol = 0.3722 g
