1. Write the overall reaction (not the mechanism) for the reaction of benzoic acid with methanol in the presence of sulfuric acid. Carbokitic acid 2. In the reaction in #1 abo Acid astyzeled metlige Acid actyzeled 3. What main peaks should be seen in the IR spectrum of the methyl benzoate? [List peaks only in the "diagnostic" region and not in the "fingerprint" region.] 4. Write the overall reaction (not the mechanism) for the reaction of methyl benzoate with excess phenyl magnesium bromide in diethyl ether, followed by \( \mathrm{H}_{3} \mathrm{O}^{+} \). 5. Why is it necessary to scrupulously oven-or flame-dry the glassware used in Grignard reactions? Support your answer with a reaction equation. \[ \text { PHMgBr }+\mathrm{HzO} \] 6. What is the purpose of adding sulfuric acid at the end of the Grignard reaction? 7. In the extraction procedures, how do you know which layer is on top and which is on bottom? 8. Suppose you ran this sequence of reactions starting with \( 8.00 \mathrm{~g} \) of benzoic acid, excess methanol, and excess phenyl magnesium bromide. What would be the expected theoretical yield of triphenylmethanol? Show all calculations. 9. Refer to \( \# 8 \) above. If \( 5.36 \mathrm{~g} \) of triphenylmethanol was isolated at the end of the reaction sequence, what would the \% yield be? 10. Is triphenylmethanol a solid or liquid at room temperature? 11. What kind of tests would you want to do (or what data you would want to report) to confirm if the final product of the reaction sequence was indeed triphenylmethanol? List 2 items. 12. If your triphenylmethanol was determined to be impure, how might it be purified? [List a general technique no details required.]
