Lab 9 Revised Experimental Procedure

The experimental procedure for Lab 9 (diazo coupling) has been revised. The diazo coupling reaction will now be performed at reflux, which precludes the need for purging the reaction flask with nitrogen. You may download the revised procedure from the Shared Files page. This procedure replaces the one found in the course manual. Use the new procedure when writing your pre-lab entry. Sorry for the late notice.
