Ans 1 : 5-methyl-2,6-heptadiene
The isolated dienes are also called as unconjugated dienes. In these alkenes , the double bonds are seperated by two or more single bonds. These alkenes are less stable than conjugated dienes.
Here the double bonds are present on 2nd and 6th positions , and 3 single bonds are present in between them.
Multiple choice questions I. Which ONE of the following compounds is an isolated diene? a) 4-methyl-13-heptadiene...
