ALKYNES
Alkyne: Any of the series of unsaturated hydro
carbons, containing a triple bond.
Alkynes have a molecular geometry that is linear with
a bond angle of 180 degrees.
Sigma bond: strongest type of covalent chemical bond.
Pi bond: covalent bond between two neighboring
atom's unbounded p-orbitals.
PICTURE SLIDE #1
#1 is a picture of a
Propyne model where the
two carbons in the middle
are triple bonded
together.
#2 is a picture of a
1-Butyne model where
the two carbons on the
end are triple bonded
(might be hard to see).

PICTURE SLIDE #2
This picture is of a.
2-Butyne model where the
triple bond is now located
in the middle instead of on
the ends.
FUN FACT
Alkynes have been used in
several medications such
as an anti-fungal,
antiretrovirals, and even
an anti-tumor drug if
bonded with an Alkene
first.

CONCLUSION
What makes Alkynes special is there ability to form the
Carbon triple bond.
Each triple bond can only have one sigma bond and
two pi bonds.
Triple bonds cannot rotate as freely due to the added
electrons.
The molecular shape of alkynes is linear.
