Isabel needs an image to represent the carbon cycle for a presentation in her science class. She has the following diagrams to c
hoose from
(A.)model A would be the best model for the carbon cycle because carbon depletes over time as it is used by different organisms.
(B. )model B would be the best model for the carbon cycle because carbon will follow the same path when it is transferred from one place to another
(C. )model ac would be the best model for the carbon cycle because the carbon cycle has definite beginning and end where carbon eventually cannot be reused
(D. )model D would be the best model for the carbon cycle because the carbon cycle is a flow of matter which can take different paths bringing carbon back to the same place

Answer:
When two single single bonds separated by a double bond (e.g C=C-C=C or C=C-C=O in the case of 2-cyclohexenone), the effect of resonance among those there bonds will be observed.
Explanation:
Since the Oxygen atom has higher electronegativity, it will cause the electrons in the resonance bonds 'flow' toward the Oxygen atom, so that the C=C will 'lose' some electron. The signal read for that bond will be different from other alkene structure.
Attachment is the resonance structure of 2-cyclohexene.
