Discuss the types of reactions given by alkynes.

(N/A) Alkynes undergo the following types of reactions:
$(a)$ Acidic character: Terminal alkynes react with strong bases due to the acidic nature of the terminal hydrogen atom.
$(b)$ Electrophilic addition reactions: Alkynes undergo electrophilic addition with reagents such as $(i)$ $H_{2}$,$(ii)$ $X_{2}$,$(iii)$ $HX$,$(iv)$ $H_{2}O$,$(v)$ $HOX$,$(vi)$ $CH_{3}COOH$,and $(vii)$ $HCN$.
$(c)$ Polymerization reactions: These include $(i)$ Linear polymerization and $(ii)$ Cyclic polymerization.
$(d)$ Oxidation reactions: These include $(i)$ Baeyer's reagent test,$(ii)$ reaction with alkaline $KMnO_{4}$ at high temperatures,$(iii)$ Ozonolysis,and $(iv)$ complete combustion in air.
