Alkynes contain triple bonds between carbon atoms from "summary" of NCERT Chemistry Class 11 - [CBSE Board] by Dr. S. C. Rastogi, ,Er. Meera Goyal
Alkynes are a class of hydrocarbons that are characterized by having triple bonds between carbon atoms. These triple bonds consist of one sigma bond and two pi bonds. The presence of these multiple bonds gives alkynes some unique properties compared to alkanes and alkenes. The triple bond in alkynes is formed by the overlap of sp hybridized orbitals on the carbon atoms. This results in a linear shape for the alkynes, with a bond angle of 180 degrees. Due to the presence of the triple bond, alkynes are relatively more reactive than alkanes and alkenes. The presence of pi bonds in alkynes also leads to res...
