Interpretation:

The reagent that is needed to convert to Organic Chemistry-Package(Custom), Chapter 11, Problem 11.38P , additional homework tip  1 each of the compound needs to be identified.

Concept introduction:

Addition of H2O to an alkyne resembles similar to the acid-catalyzed addition of H2O to an alkene. In the presence of strong acid or Hg2+ catalyst, the elements of H2O add to the triple bond, an initial addition product of an enol is formed, which is an unstable product and rearranges to a product containing a carbonyl group-that is, a C=O. A carbonyl compound having two alkyl groups bonded to the C=O carbon is called a ketone product as shown below in the fig.

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.

Interpretation:

The reagent that is needed to convert to Organic Chemistry-Package(Custom), Chapter 11, Problem 11.38P , additional homework tip  5 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 alkane product as shown below in the fig.

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 alkyl halides and epoxides by nucleophilic substitution reaction is shown below in the fig.
