Topic walkthroughs, sample sessions, and reference material for general and organic chemistry. Open any topic to launch the whiteboard — or start blank and save your own.
Each topic links to the whiteboard. Drop in the relevant stamps and elements from the side panel — periodic table on the right tab, chemistry stamps on the left.
Mole-to-mole ratios, limiting reagents, percent yield. Use the periodic table for atomic masses; switch on the grid for balanced equations.
Open whiteboard →pH, pKa, conjugate pairs, buffer calculations. Subscripts and superscripts via the X₂ / X² buttons; auto-format with the ⚗ button.
Open whiteboard →ΔH, ΔS, ΔG, Hess's law. Use multiple pages — one for the energy diagram, one for the work-through.
Open whiteboard →Kc, Kp, ICE tables, Le Chatelier. Pages for each shift; stitch the PDF when you're done.
Open whiteboard →Substrate, nucleophile, leaving group, solvent. Use the benzene and arrow-push stamps to map mechanisms cleanly.
Open whiteboard →Chemical shifts, splitting patterns, integration. Sketch out spectra on one page; assign protons on the next.
Open whiteboard →R/S, E/Z, chair conformations, Newman projections. Big workspace — use fullscreen and the chair-stamp shortcut.
Open whiteboard →Hückel's rule, conjugation, resonance arrows. The benzene stamp + arrow push tools were built for this topic.
Open whiteboard →Aldehydes, ketones, esters, amides. Acid/base catalyzed mechanisms — page through them step-by-step.
Open whiteboard →When you save a whiteboard as PNG or PDF, the file downloads to your device. Save here, re-open with any PDF viewer, or print and annotate.
