Alkanes and Alkynes

Alkanes and alkynes are just like organic compounds but the carbons in the molecular structure will most likely form double and triple bonds

Ex 1. CH2 = C = CH2 double bonds in the naming is signified by putting the placement in front of the carbon chain which is at the end. In this structure there are two double bonds, one and 1 and the other at 2, with a carbon pain of 3.
1,2 – propene the ending for propane is changed to ene to signify that there is a double bond

Ex 2.          CH3
            l
CH3 – CH – CH = C = CH2
The  longest carbon chain is 5, double bonds are located first and second, and a branch is 4 from the most left point, with one carbon in the branch.
Name of the structure: 4 – methyl – 1,2 – pentene
Ex 3.          CH3
           l
CH3 – C = C – CH2 – CH3
   l
  CH3
The longest carbon chain is 5, double bond is located on the third, and there are two branches, one on the third and fourth from the most right with one carbon on each branch
Name of the structure: 4 – methyl – 3 – methyl – 3 – pentene
