9. Show two pathways to synthesize cyclopentyl ethyl ether using the Williamson ether synthesis. Which one is preferred and why? (4 pts)
13. Briefly explain why the following hypothetical reaction is unlikely to occur. (4 pts) на I is a terpene found in cinnamon, sassafras, and orange flower oils. A possible retrosynthesis step for linalool is shown, starting with an octene carbonyl.Show a forward synthetic route here using this octene carbonyl and ethyne (CHa) as a source of the two additional carbons. If your synthesis involves a step that makes multiple products, show them all and assume that you have the ability...

need work and answers 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...
1) Choose one molecule from the set and create an 8-step synthesis scheme using the chosen molecule as your starting material. You need to write the complete set of reagents and draw the product expected from each step. Reagents typically used together are considered one step, eg. 1) LAH 2) H.O should be considered as one step Your 8 steps must include at least one reaction from each of the chapters, aldehydes and ketones, carboxylic acid derivatives, alcohols. You can...

Synthesis using Carbonyla-Substitution Chemistry Preamble This experiment involves the synthesis of target molecules using a-substitution chemistry. You are assigned two target molecules, one of which is best synthesized by an alkylation approach, while the other is best synthesized by an addition or condensation approach. My two target molecules are number 2 and number 12 in the last page. You must do the following: 1. Perform a retrosynthetic analysis on the two target molecules assigned to you. In each case the...
