Answer:
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.
