Question

what are alkynide and how they are formed
​

Answer 1

Answer:

Alkynide Anion Formation. First, the terminal alkyne must be deprotonated with a strong base, such as sodium amide (NaNH2). This proton can be removed because terminal alkyne hydrogens are more “acidic” than alkene or alkane hydrogens. This forms the alkynide anion, which is a great nuleophile.
