Your answer must employ the following reagents: methylene chloride, hydrochloric acid (1M & 6M), sodium hydroxide (1M & 6M), 10% sodium bicarbonate (aq). Clearly indicate the product(s) and layers formed following each step of your separation scheme. IMPORTANT: p-cresol is soluble in sodium hydroxide solution but insoluble in neutral water or sodium bicarbonate solution. 2-ethylbenzoic acid is soluble in both sodium hydroxide and sodium bicarbonate solutions.

IlI. Preparation of Synthetic Eugenol (10 pts) Eugenol, the main component of clove oil, can be prepared from heating 2-allyl guaiacol (in the absence of oxygen) to temperatures>205 °C. In practice, however, it is most cost effective to extract eugenol from cloves, its natural source. Given a weight percentage of eugenol in cloves at-15%, calculate the minimum mass of cloves one needs to obtain 1.00 g of eugenol as product? Report your answer below. Show your...

Predict which proton in ascorbic acid is the most acidic.
Identify the appropriate atom by selecting each atom and
assigning it a map number of 1 until all atoms are mapped. To do
this, right-click on an atom and choose Atom Properties. (Mac
users: Use an equivalent for right-clicking.) Then, clear the
check mark to enable the Map field before entering a value.
