Concept explainers
(a)
Interpretation: The class of given cycloocta-1,4-diene as isolated, conjugated, cumulated, or a combination is to be stated.
Concept introduction: Conjugated systems have alternate single and double bonds that results in lower the energy and increase the stability of a molecule. Isolated dienes or polyenes are the compounds that comprise double bonds at the large distances separated by more than one single bond, whereas cumulated dienes or polyenes are the compounds that do not possess any single bond in between the two double bonds.
