Eugenol is the component responsible for the odor of cloves, which are dried flower buds of theevergreen tropical tree Eugenia aromatica. The isolation of eugenol from the rest of the constituents of"oil of cloves" (comprising around 10% of acetyleugenol and caryophyllene) is highly dependent on thechemically active proton of the phenolic group of eugenol. Draw the structure of the main componentsof "oil of cloves" and describe how to isolate or extract eugenol considering its structure.

The sex attractant of the housefly has the formula C23H46. When treated with warm potassium permanganate, this pheromone gives two products: CH3(CH2)12COOH and CH3(CH2)7COOH. Suggest a structure for this sex attractant. Explainwhich part of the structure is uncertain
A common illicit synthesis of methamphetamine involves an interesting variation of the Birch reduction. A solution of ephedrine in alcohol is added to liquid ammonia, followed by several pieces of lithium metal. The Birch reduction usually reduces the aromatic ring, but in this case it eliminates the hydroxy group of ephedrine to give methamphetamine. Propose a mechanism, similar to that for the Birch reduction, to explain this unusual course of the reaction.

Both pyridine and pyrrole are nitrogen containing aromatic heterocyclic compounds. When treated with HCl, only pyridine forms the hydrochloride salt, where as pyrrole is unreactive. What is the best explanation for this observed reactivity.
Why does cyclohexanol have a pK, of 18 and phenol, despite its similarities in structure, have a pK, of 10? Phenol has a resonance-stabilized conjugate base, which increases the stability of the base and favors its formation Cycohexanol has a resonance-stabilized structure, which increases its stability and reduces the likelihood that it will react to form a conjugate base Phenol has a resonance-stabilized conjugate base, which decreases the stability of the base and inhibits its formation Cycohexanol has a resonance-stabilized conjugate base, which increases the stability of the base and favors its formation Phenol has a resonance-stabilized conjugate base, which decreases the stability of the base and favors its formation
