Chemical reactivity of alkynes - Hydrocarbon
C Ξ C is less reactive as compared to the carbon-carbon double bond in the direction of electrophilic addition reaction. This is reason in alkyne carbon has much more S-character much more strongly will be the attraction for Π electrons. Alkyne also undergoes nucleophilic addition along with electron rich reagents.
