Interpretation:
The structures of each intermediates and of muscalure formed in the reaction are to be given.
Concept Introduction:
The reaction of
Electrophiles are electron deficient species which has positive or partially positive charge. Lewis acids are electrophiles which accept electron pair.
Nucleophiles are electron rich species which has negative or partially negative charge. Lewis bases are nucleophiles which donate electron pair.
Free radical is an atom, molecule or ion that has unpaired electrons which makes it highly chemically reactive.
Substitution reaction: A reaction in which one of the hydrogen atoms of a hydrocarbon or a
Elimination reaction: A reaction in which two substituent groups are detached and a double bond is formed is called elimination reaction.
Addition reaction: It is the reaction in which unsaturated bonds are converted to saturated molecules by the addition of molecules.
Carbocation is a molecule having a carbon atom bearing three bonds and a positive formal charge.
Carbocation are generally unstable because they do not have eight electrons to satisfy the octet rule.
The order of stability of carbocation is such that the tertiary carbocation is the most stable whereas the primary carbocation is the least stable, and secondary carbocation lies between primary and tertiary carbocations.
If primary carbocation is obtained in product, it rearranges itself to secondary or tertiary carbocation to form more stable product.
If secondary carbocation is obtained in product, it rearranges itself to tertiary carbocation to form more stable product.
The stability of carbocation:

- Eugenol is the component responsible for the odor of cloves, which are dried flower buds of the evergreen 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 the chemically active proton of the phenolic group of eugenol. Draw the structure of the main components of "oil of cloves" and describe how to isolate or extract eugenol considering its structure.arrow_forwardPropose a reasonable synthesis of the following reaction:.arrow_forwardGive the suitable synthesis to accomplish the following transformation.arrow_forward
