Q 6 - (2 pts) Cyclopropanone is highly reactive because of its large amount of angle strain. But methylcyclopropenone, although even more strained than cyclopropenone, is nevertheless quite stable and can even be distilled. Give the best explanation to stability of methylcyclopropenone, taking the polarity of the carbonyl group into account. A) carbonyl is conjugated with double bond of cyclopropene ring stabilizing the system B) resonance structure of methylcyclopropenone has cyclopropene cation moiety, which appears to be aromatic C) resonance structure of methylcyclopropenone has cyclopropene cation moiety, which appears to be antiaromatic D) methylcyclopropenone is a trisubstituted alkene stabilized by hyperconjugation effect.
