1-Phenylethanol undergoes an esterification with propionic anhydride in the presence of the enantioselective catalyst (S)-HBTM. The products of the reaction are analyzed by thin-layer chromatography (TLC). Which of the given statements about TLC are correct? The silica stationary phase is nontoxic, so TLC plates can be handled by their faces with bare hands. A comparison of the relative areas of the developed spots of the ester and unreacted alcohol can lead to an estimate of the amount of conversion. Assuming that there is 1.2 cm of ethyl acetate/hexanes solvent system at the bottom of the TLC tank, the ideal height at which to spot your samples on the TLC plate is 1.1 cm. The phosphomolybdic acid stains the spots green. The alcohol has a lower R; value than the ester product. The samples in lanes 1 and 2 should be spotted so close to each other that they are almost touching.

Imagine that phenol (“hydroxybenzene”) and nitrobenzene are reacted (in separate beakers) with a hot solution containing both concentrated sulfuric acid and concentrated nitric acid. A) In analyzing the products, you discover that the substitution pattern resulting from the reaction with phenol differs from the reaction with nitrobenzene. Explain this difference in substitution patterns using one or more judiciously selected reaction mechanisms or portions of mechanisms.

The mechanism of the Fischer esterification was controversial until 1938, when IrvingRoberts and Harold Urey of Columbia University used isotopic labeling to follow thealcohol oxygen atom through the reaction. A catalytic amount of sulfuric acid was addedto a mixture of 1 mole of acetic acid and 1 mole of special methanol containing the heavy18O isotope of oxygen. After a short period, the acid was neutralized to stop the reaction,and the components of the mixture were separated.H2SO4OCH3 C O H CH3 O H CH3 C O CH3 H2OO18 + +(a) Propose a mechanism for this reaction.(b) Follow the labeled 18O atom through your mechanism, and show where it is found inthe products.(c) The 18O isotope is not radioactive.
