Maleic Anhydride 3D Model — CAS 108-31-6

Maleic Anhydride (C4H2O3, CAS 108-31-6) — a free educational 3D molecular model for teachers and students, by MolGod.org. Whatever the filament colour, each atom reads clearly thanks to its engraved symbol. Look at the skeleton first: Maleic Anhydride contains one 5-membered ring, and students can trace 9 bonds (6 single and 3 double). Give each pair of students the model and a blank sheet: recording every engraved symbol should lead them to 4 C + 2 H + 3 O, which is 9 atoms. Students meeting the carbonyl group (C=O) for the first time can hold an example in their hands.
