A collection of nine chemical structures arranged in a grid-like pattern. Each structure is represented by a hexagon-shaped molecule with a different chemical formula written on it. The first structure on the top left is a carbon atom with a nitrogen atom attached to it. The nitrogen atom is labeled with the letters "NC" and "CN" on it, indicating that it is a nitrogen molecule. The second structure in the top right is a hexagonal molecule with the letter "R" on the left side. The third structure is a double bond molecule with two carbon atoms attached to each other. The fourth structure is an oxygen molecule with three carbon atoms on the right side. Lastly, the fifth structure is another carbon atom, labeled as "R", with a single carbon atom in the center. The sixth structure is also labeled as a hydrogen atom with two hydrogen atoms on either side. All the structures are drawn in black and white and appear to be hand-drawn.
