Locker A-15 Mondays 12:00 PM April 22, 2007 Unknown Lab Introduction: In this five week la, we were given two compounds, one which was a ketone and the other was an aldehyde. The purpose of this lab was to find out which compound was a ketone and which was an aldehyde through a Tollen’s test and then finally correctly identify what the ketone is and what the aldehyde is. This process is done by taking melting points and boiling points of the compounds and also by taking DNP and semicarbazone derivatives and then finding their melting points. The final part of this lab is to react the ketone with the aldehyde to form a pure aldol product that is to be handed in. Main Reaction: + Table of Data: Compound Number 718 739 Boiling Point 78º C 238º -240º C Tollens Test Negative (ketone) Positive (aldehyde) Iodoform Positive N/A DNP MP 105º-110º C 248º-252º C Ring conjugation No N/A Semicarbazone MP 125º -128º C 198º-202º C Compound 2-butanone 4-methoxybenzaldehyde Procedure: 1. The first test that was performed on the compounds was the boiling point test. Since both of the compounds were liquids, it was not necessary to perform a melting point test on the compounds. 2.
