How to Make a Molecule

Step 1: Know all the atoms in the target molecule, how they connect to each other, and how they fit together in 3-dimensional space

Step 2: Choose a few starting materials (atoms) and pour or scoop them one-by-one into a glass flask

Step 3: Design a series of chemical reactions that will convince the atoms to form the target molecule by attaching at the correct places, releasing unneeded parts, or correctly swapping one atom for another
