Fit flasks, condensers and adapters at their true ground joints, or start from a distillation, reflux or Soxhlet setup. Save the apparatus as an SVG that opens again.
Take a picture of a plate and read its Rf values, then weigh the eluent on a solvent scale. The same reader is a panel of draw.cheminfo.org.
Point at a protein and read which helix or strand it is, with its length, its atoms and its backbone hydrogen bonds.
Draw structures, reactions and mechanisms, and keep them as an SVG that still knows its chemistry.
Find the structure of a molecule from its infrared, mass and NMR spectra, then draw it and check it.
Every constitutional isomer of a formula, at a name that says so. Each surge.cheminfo.org link opens the same page on the new address.
Open the measured titration curves of malonic, succinic, glutaric, maleic and tartaric acid.
A chat client speaking MCP can compute conformers, Hückel orbitals, pH and titration curves, element data, property predictions, isomer counts and InChIs, and shows each answer as a card.
Open measured IR and Raman spectra in tabs of their own, beside the spectra GFN2-xTB computes in your browser.
Every compound of a Wikipedia article with a Chembox or a Drugbox, with the values of its infobox, found by a drawn fragment.
Paste the link a Share button gives, and the tool covers the slide, live, in front of the class.
Add ?seed=each to an exercise link and no two students who open it work on the same series.
Natural products and tested compounds from the open databases: the organisms each was found in, and every assay result.
Count electrons and assign oxidation states on atoms, balance reactions on moles, and name inorganic compounds on inorganic, with graded exercises on each.
Draw a molecule and compute its infrared and Raman spectra with GFN2-xTB, on your own computer.
Read the degree of unsaturation from a formula or a structure, assign a point group one question at a time, and predict toxicity risks and drug scores.
Ask one real chemical dataset the same question in SQL and in Mango, in the browser, and compare the two answers.
Every cheminfo tool, by topic, with what is new on each and the classic visualizer views. This page needs JavaScript; every tool it lists is a link of its own.
