You indicate the triple bond by three parallel lines between the two atoms, and the bond angle between the atoms attached to them should be 180 °.


Remember that he location of the triple bond is indicated by the number of the first carbon atom of the triple bond.

If the triple bond is at atom #n#, the bonds to atoms #n-1#, #n#, #n+1# and #n+2# must all be in a straight line,

For example, the structure of hex-3-yne is

Note that atoms 2, 3, 4, and 5 are in a straight line.

Atoms 2 and 5 are #sp^3# hybridized , so the bonds to them are at angles.


Draw the structure of non-4-yne.


Draw atoms 3, 4, 5, and 6 in a straight line, with a triple bond between atoms and 4.

Add atoms 1, 2 and 7, 8, 9 as zig-zag lines to the skeleton structure.

And you have the structure of non-4-yne.
