Aldehydes & Ketones
Aldehydes & Ketones • Aldehydes and ketones are characterized by the the carbonyl functional group (C=O) • The compounds occur widely in nature as intermediates in metabolism and biosynthesis Aldehydes and Ketones • The functional group of an aldehyde is a carbonyl group bonded to a H atom ...
Experiment #9 - Identification of Aldehydes and Ketones
A positive test for an aldehyde will be a silver mirror formed on the test tube if the test tube was clean; if the test tube was not clean, a black precipitate will form.
