Nick Kim-Alkene and Alkyne

This time we are going to find unsatrured hydrocarbon, means they are not single bond.

Alkene= double bonded
Alkyne=triple bonded

Naming is simialr to the alkane, you just need to put -ene instead of -ane. Same as alkyne -ene instead of -ane.

Ex,2-hexene

first you write down the number of carbon which is 6

c c c c c c

the 2 represent where double bond is

c-c=c-c-c-c

then put hydrogen

CH3-CH=CH-CH2-CH2-CH3

Notice where second carbon and third carbon only have one hydrogen.

Alkyne= Triple bond

This is very similar to the double bond

ex, 3-Hexyne

 Same as alkene, the number represent where the bond is, and it's triple, thus there is no hydrogen in third and fourth( between fourth and fifth sould be - sorry)
