1-(2-Hydroxyethyl)piperazine — CAS 103-76-4

1-(2-Hydroxyethyl)piperazine (C6H14N2O, CAS 103-76-4) — a free educational 3D molecular model for teachers and students, by MolGod.org. Instead of colour coding, every sphere carries its engraved element symbol. Start with the ring system: 1-(2-Hydroxyethyl)piperazine has one 6-membered ring; in total the model carries 23 bonds (all of them single). Hand the model round and let students tally the engraved atoms: 6 C + 14 H + 2 N + 1 O, 23 in total. Pair it with 1-(2-Methoxyethyl)piperazine (CAS…
