Alkyne Reactions Review

Flashcards to help review and memorize key concepts regarding alkyne reactions and their mechanisms.

What are the two types of alkynes discussed in the lecture?

Internal alkynes and terminal alkynes.

How do internal alkynes generally react in oxidation?

All products are the same, regardless of the process used.

What is a key requirement for hydroboration oxidation to produce an aldehyde from an alkyne?

The alkyne must be terminal.

What type of alkyne is needed to create a ketone using hydroboration oxidation?

An internal alkyne.

What special reaction can transform a terminal alkyne into a carbon chain?

Alkylation using acetylide anion and primary alkyl halide.

What is the stereochemical outcome of an SN2 reaction?

Inversion of configuration at the stereocenter.

What is the relationship between nucleophilicity and basicity in reacting species?

Better bases are generally better nucleophiles.

Which group on an alkyl halide can be replaced in a substitution reaction?

The leaving group.

What is the role of a base in SN2 reactions?

It acts as the nucleophile to attack the electrophile.

In the context of alkyne reactions, what does oxidation yield?

Carbonyl compounds.
