Positive Test for C3H6O
Silver Mirror Test
The silver mirror test is commonly used to detect the presence of aldehydes. When an aldehyde reacts with Tollen's reagent, a silver mirror is formed on the inner surface of the test tube. However, the compound C3H6O did not give a silver mirror with Tollen's reagent, indicating that it is not an aldehyde.
Formation of Oxime
The compound C3H6O reacted with hydroxylamine to form an oxime. An oxime is a compound that contains a nitrogen-oxygen double bond (-C=N-OH) and is formed by the reaction of a carbonyl compound with hydroxylamine. This reaction is specific to compounds that have a carbonyl group, such as ketones and aldehydes.
Positive Test for Ketones
Since C3H6O did not give a silver mirror with Tollen's reagent, it is most likely a ketone. Ketones do not give a positive silver mirror test because they lack the necessary hydrogen atom to reduce the silver ions in Tollen's reagent. Instead, ketones react with hydroxylamine to form oximes.
