Part I

First, measure out the necessary reagents.

Write down the quantities in your lab notebook.

8-anilino mass

The photo shows a plastic weighing boat on top of a laboratory scale. The contents of the weighing boat are barely visible, but there appears to be a medium-sized pile of yellow solids. The screen on the scale reads “0.4681 g.”

sodium hydroxide volume

The photo shows a translucent plastic reagent bottle on an aluminum foil-covered tray. The label on the bottle is not visible, but a plastic syringe is inserted into the top. The plunger on the syringe is withdrawn to the 1.0 mL mark, filling the syringe with clear liquid.

Dissolve the coupling agent in the sodium hydroxide solution and cool the mixture on ice.

The photo shows a gloved hand holding a small Erlenmeyer flask just above the surface of a magnetic stir plate. The flask contains a very small portion of homogeneous, dark yellow solution.

You're finally ready to add the nucleophile to the diazonium electrophile you made!
