Organic Chemistry
3D learning labs.
Connect separation methods with electron delocalisation, structure and reactivity through interactive visual laboratories.
TOPIC CLUSTER
Learn the branch as connected ideas.
The Organic Chemistry cluster now connects practical purification and characterisation with electronic structure. Explore column, thin-layer and paper chromatography, then move from p-orbital overlap and curved-arrow movement to canonical contributors, charge delocalisation and the real resonance hybrid.
TLC, paper and Rf analysis
Develop spots visually, measure from a common baseline and calculate unitless Rf values under matched conditions.
Resonance and delocalisation
Inspect p-orbital alignment, canonical contributors, fractional bond order and charge maps to connect resonance with structure and reactivity.
LIVE SIMULATIONS
Open a focused visual lab.
LAB 11General Organic Chemistry
Resonance 3D Lab
Connect aligned p-orbital overlap with imaginary canonical contributors and the real resonance hybrid across 23 important conjugated systems.
LAB 17Purification & Characterisation
Chromatography 3D Lab
Run column, thin-layer and paper chromatography in 3D, compare stationary and mobile phases, and measure separation with an interactive Rf calculation.
STUDENT QUESTIONS
Common questions about organic chemistry.
Which Organic Chemistry 3D labs are available?
The Chromatography 3D Lab covers column, thin-layer and paper methods with interactive Rf measurement. The Resonance 3D Lab covers p-orbital overlap, canonical contributors, curved-arrow movement, fractional bond order and charge delocalisation.
How does the chromatography lab compare the three methods?
It separates the shared principle from each method: column and TLC emphasise adsorption on a solid, while paper chromatography emphasises partition between stationary water and the moving solvent.
Can I calculate Rf in the chromatography simulation?
Yes. The TLC workflow lets you develop the chromatogram, select measurements and calculate Rf from the component and solvent-front distances measured from the same baseline.
Is a canonical form a real molecule?
No. Canonical contributors are valid drawings used to represent electron delocalisation. The experimentally real species is the resonance hybrid.
Which learning levels does the Resonance 3D Lab support?
It covers both foundational and advanced resonance ideas used in General Organic Chemistry.
