1. When answering the following questions draw i.e. make use of the structures of benzoic acid and ethyl-4-aminobenzoate which are presented on page 15 of the textbook ( A miscroscale approach to orgganic chem)

i) Consider a test tube containing benzoic acid to which was added 1.0 M NaOH. Write the balanced chemical equation representing this reaction.

Now write the balanced chemical equation describing the reaction when 6.0 M HCl is added to the above resultant solution.

ii) Consider a test tube containing ethyl 4-aminobenzoate to which was added 1.0 M HCl. Write the balanced chemical equation representing this reaction.

Now write the balanced chemical equation describing the reaction when 6.0 M NaOH is added to the above resultant solution.  

2. You have been provided with a dichloromethane or methylene chloride (CH2Cl2) solution of aspirin and amphetamine whose structures are shown on the right. Provide your answer with the appropriate details regarding what would happen to each compound in the two phases (organic and aqueous). Write the correct chemical equation to illustrate each answer.

i) What would happen if this solution was shaken with an aqueous solution of I M HCl? Explain with chemical equation.

Would you have separated the two compounds?                        State either yes or no in the adjacent blank.

What would happen if this solution was shaken with an aqueous solution of I M NaOH? Explain with chemical equation.

Would you have separated the two compounds?                        State either yes or no in the adjacent blank.

Explanation / Answer

C7H6O2 + NaOH ----> C7H5O2 Na + H2O

C7H5O2Na + HCl ----> C7H6O2 + NaCl

C9H11NO2 + HCl -----> C9H12NO2 + Cl--

C9H12NO2 + Cl-- + NaOH---->
