I have determined one of my unknowns to be benzophenone and in a lab setting (but that isn't possible because of COVID-19) I would conducted the 2,4 DNP test which should yield a positive result. However, I am a bit stuck on other tests that would make it very definitive that a ketone is present.
I know if I use the following test, I would get the following results:
- The Tollen's test- it would be negative because an aldehyde isn't present
- The iodoform test- would be negative because the ketone on benzophenone would be negative
- The Chromic Acid test- would be negative because Aldehydes are oxidized by chromic acid, ketones are not.
But are there any other tests that can be used?
I have seen the previous post on this question dated back to 4 years ago and it didn't really help.
