SUMMARY

The discussion centers on the behavior of ketones in relation to isomerism, specifically metamerism. It is established that higher ketones exhibit metamerism due to larger substituents, while some sources claim that lower ketones also demonstrate this property. The conversation highlights the differences between propanone, butanone, and pentanones, emphasizing that while propanone and butanone have unique structures, pentanones possess multiple isomers. The importance of visualizing these structures is underscored for better understanding.

PREREQUISITES
  • Understanding of ketone structures and nomenclature
  • Knowledge of isomerism types, particularly metamerism
  • Familiarity with drawing organic molecular structures
  • Basic grasp of carbon chain length effects on isomerism
NEXT STEPS
  • Research the concept of metamerism in organic chemistry
  • Study the structural differences between propanone, butanone, and pentanones
  • Learn about the various isomers of ketones with five or more carbon atoms
  • Explore molecular visualization tools for organic compounds
USEFUL FOR

Chemistry students, organic chemists, and educators seeking to deepen their understanding of ketone behavior and isomerism.

In an article I read that higher ketones show metamerism because of larger substituents but still other websites reveal that they show metamerism irrespective if lower or higher? help please
thanks
i hope mr. borek don't find fault with it now kindly...

I told you to consider the differences between propanone, butanone and pentanones. There is only one propanone and butanone, but several ketones containing five carbon atoms (and many more isomers of every ketone containing more carbons). Try to draw them and see for yourself why it is the case.

You have again posted in a wrong forum, plus, what you did now counts as a crosspost, you should post in the old thread. You were told several times to read the forum rules, you are still not following them. I don't want to ban you, but with each post you are leaving me with less and less options. From now on your every post not following the rules will be deleted.
