Classify the following dienes and polyenes as isolated, conjugated, cumulated, or some combination of these classifications. a. cycloocta-1,4-diene
b. cycloocta-1,3-diene
c. cyclodeca-1,2-diene
d. cycloocta-1,3,5,7-tetraene
e. cyclohexa-1,3,5-triene (benzene)
f. penta-1,2,4-triene

cycloocta-1,4-diene- isolated double bond

cycloocta-1,3-diene- conjugated double bond

cyclodeca-1,2-diene- cumulated double bond

cycloocta-1,3,5,7-tetraene- conjugated double bond

cyclohexa-1,3,5-triene (benzene) - conjugated double bond

penta-1,2,4-triene- cumulated and conjugated double bond

Explanation:

A conjugated double bond is a system that contains alternate double and single bonds. It is renowned for its unusual stability.

A cumulated double bond is a double bond system involving about three atoms e.g C=C=C.

An isolated double bond is a system of double bonds separated by more than one single bond.
