(R)-(-)-1-CBZ-3-pyrrolidinol 3D Molecular Model — CAS 100858-33-1

(R)-(-)-1-CBZ-3-pyrrolidinol (C12H15NO3, CAS 100858-33-1) — a free educational 3D molecular model for teachers and students, by MolGod.org. Every sphere shows which element it is through an engraved symbol, not a colour code. Ask students to describe the framework of (R)-(-)-1-CBZ-3-pyrrolidinol before anything else: two rings (one 5-membered and one 6-membered), one of them aromatic. Then count the bonds together; there are 32 (25 single, 1 double and 6 aromatic, drawn in Kekulé form). Give each pair of students the model and a blank sheet: recording every engraved symbol should lead them to 12 C + 15 H + 1 N + 3 O, which is 31 atoms. Functional groups to find on the model: carbamate group (-NH-CO-O-) and hydroxyl group (-OH). Stereochemistry in your hand: (R)-(-)-1-CBZ-3-pyrrolidinol carries one stereocentre (R), so students can check each label against the CIP rules. Use it when you teach aromaticity and delocalised electrons, chirality, enantiomers and CIP (R/S) rules, the carbonyl group (C=O), as well as alcohols and hydrogen bonding. Part of the MolGod.org free library of engraved molecules for chemistry classrooms. Teachers: print one per group and let students check the structure against the formula.
