The alkylation of an alkynide ion procedes via a(n) Choose your answer here reaction.

The alkylation of an alkynide ion proceeds via a nucleophilic substitution reaction.

Here are the steps:

1. Deprotonation of Alkyne: The first step in the alkylation of an alkynide ion is the deprotonation of the alkyne to form an alkynide ion. This is done by using a strong base like sodium amide (NaNH2) to remove a proton (H+) from the alkyne.

2. Nucleophilic Attack: The negatively charged alkynide ion then acts as a nucleophile, or electron donor, and attacks an electrophile, which is typically an alkyl halide. The alkynide ion forms a bond with the alkyl group, displacing the halide ion in the process.

3. Protonation: Finally, the alkynide ion is protonated to form the final alkylated alkyne product. This is typically done by adding water or another suitable proton source.

So, the alkylation of an alkynide ion proceeds via a nucleophilic substitution reaction.
