give examples of nucleophilicaddition reaction of alkynes.

Hi,

Example of nucleophillic addition reaction of alkyne is given below :

Alkyne undergo nucleophillic addition reaction with active hydrogen containing compound like HCN , Alcohol etc to form derivative.

$$\begin{gathered} {\text{1) CH≡CH + H-CN →CH}}_2\text{=CHCN} \\ 2) \mathrm{CH}\equiv \mathrm{CH} + {\mathrm{CH}}_3\mathrm{OH} \to {\mathrm{CH}}_2={\mathrm{CHOCH}}_3 \end{gathered}$$
