(a)
Interpretation:
The reagent that is needed to convert to each of the compound needs to be identified.
Concept introduction:
Addition of H2O to an
(b)
Interpretation:
The reagent that is needed to convert to each of the compound needs to be identified.
Concept introduction:
Addition of 1. R2BHand 2. H2O2, OH- reagent to an alkyne is a hydroboration-oxidation reaction to form the keto product as shown below in the fig. Addition of borane forms an organoborane. Oxidation with basic H20 2 forms an enol. Tautomerization of the enol forms a carbonyl compound. The overall result is addition of H2O to a triple bond.
(c)
Interpretation:
The reagent that is needed to convert to each of the compound needs to be identified.
Concept introduction:
Reaction between the 3-hexyne and HBr reagent is an example of electrophilic addition. The alkynes undergoes addition reaction because of pi bond in them. The electrophilic end of the reagent is attracted to the electron rich triple bond. It is a sequential reaction in which the addition of the reagent to alkyne to alkene which then addition of one more equivalent reagent to form the four new bond as
(d)
Interpretation:
The reagent that is needed to convert to each of the compound needs to be identified.
Concept introduction:
Terminal alkynes are readily converted into acetylide anions using the strong bases such as NaNH2 and NaH. These anions are strong nucleophiles, capable of reacting with electrophiles such as
