SN1 or SN2 — watch a substitution happen bond by bond.
Nucleophilic substitution is the first true mechanism of organic chemistry, and these simulations let you hold it in your hands: scrub along the reaction coordinate and watch the nucleophile attack a haloalkane in real time — the one-step SN2 backside strike with its umbrella-flip inversion, or the two-step SN1 route through a planar carbocation. Change the substrate from methyl to tertiary and see the energy profile, the rate law and the stereochemistry all switch over, exactly as the textbook says they must.
Beyond the open showcase, subscribed schools get the growing library of Haloalkanes & Haloarenes experiments — searchable, tagged by concept and difficulty, and expanding continuously.
