5 Summary of Organic Nomenclature -- Part 20
Also applies to internal alkynes.
The weakly acidic acetylenic hydrogen of a terminal alkyne is replaced by a metal atom.
Any compound with a triple bond.
A carbon atom of a carbon-carbon double bond is bonded to an alcohol with the hydroxy group.
The catalyst for the hydrogenation of alkynes to cis alkenes is heterogeneous.
In its most common form, it consists of a thin coating of palladium on barium sulfate.
The group is called the 1,2-dimethylpropyl group.
The triple bond is only added once with Disiamylborane.
A double bond and a protons can quickly convert from one site to another.
A carbon-carbon triple bond is often used to create vinyl cations.
Each skill is followed by problem numbers.
Draw correct structures when given their names.
The observed products of alkyne reactions can be explained by mechanisms.
Predict the products of additions, oxidations, reductions, and cleavages of alkynes.
In one-step and multistep Problems 9-30, 32, 34, 35, 36, 37, you can use alkynes as starting materials and intermediates.
Determine the structure of an unknown alkyne from the products it forms.
Structural formulas can be written for the following compounds.
The following compounds have common names.
The IUPAC names for the compounds should be given.
Show how you would synthesise the following compounds by using hex-1-ene as your starting material.
Show how you would synthesise the following compounds by using cyclooctyne as your starting material.

You can use any additional reagents.
A useful synthesis of aldehydes is the following functional-group interchange.
This method can be illustrated with an example.
The following sequence can be used to accomplish this functional-group interchange.
Explain how ethoxide adds to an alkyne more easily than it adds to an alkene.
The structure of each compound should be deduced from the information given.
The unknowns in this problem have a formula called C8H12.
