Diallylidene pentaerythritol, C₁₁H₁₆O₄, 78-19-3

Diallylidene pentaerythritol (C11H16O4, CAS 78-19-3) — a free educational 3D molecular model for teachers and students, by MolGod.org. No legend required: the element symbol is engraved on each atom. Look at the skeleton first: Diallylidene pentaerythritol contains two 6-membered rings, and students can trace 32 bonds (30 single and 2 double). Quick starter: ask students to count the engraved symbols (11 C + 16 H + 4 O) and check that they add up to 31 atoms and the formula C11H16O4. Worth bringing out when the syllabus reaches chirality, enantiomers and CIP (R/S) rules.
