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.
