how to explain this question?From: 15.31Cyclopropanone is highly reactive because of its large amount of angle strain. but methylcyclopropenone, although even more strained than cyclopro-panone, is nevertheless quite stable and can even be distilled. Explain, taking the polarity of the carbonyl group into account.
