Alkynes are hydrocarbons containing a carbon-carbon triple bond. They have the general formula CnH2n-2 and the bond angle around the triple bond is linear at 180 degrees. The triple bond consists of one sigma bond from overlapping s orbitals and two pi bonds from overlapping p orbitals. Unlike single bonds, triple bonds do not rotate freely due to the rigid nature of the pi bonds.

Unlike C-C single bonds, C-C
triple bonds do not rotate
freely, because the two pi

two nuclei.

also known
as
acetylenes,
because
ethyne
(C2H2) is also
called
acetylene.
6. 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.
