Alkynes
 Alkynes- Hydrocarbons that           Triple bonds are made up of
  have a triple bond between            one sigma bond and two pi
  two carbon atoms                      bonds. The sigma bond is the
 Have the general formula              overlapping of the s orbitals of
  CnH2n-2                               the two atoms, while the pi
 The molecular geometry                bonds are the overlapping of
  around the C to C triple bond         the two p orbitals.
  in an alkyne is linear. Thus, the    A triple bond can only contain
  bond angle around a triple            one sigma bond because there
  bond is 180属                          is only one s orbital in each
                                        atom.
                                       Unlike C-C single bonds, C-C
                                        triple bonds do not rotate
                                        freely, because the two pi
                                        bonds are not in between the
                                        two nuclei.

2-Butyne
 Alkynes are
  also known
  as
  acetylenes,
  because
  ethyne
  (C2H2) is also
  called
  acetylene.
Conclusion

 The main characteristic of alkynes
  is their Carbon to Carbon triple
  bond. This bond is linear and
  includes one sigma and two pi
  bonds.

            -Yeah, I know alkynes of them!
