SN1 Reaction Mechanism: Simple Steps

We cover the complete mechanism for SN1 in organic chemistry step-by-step, showing exactly how the leaving group departs, how the nucleophile attacks the alpha carbon, and why the whole process leads to a mixture of enantiomers. Using clear diagrams and curved arrows, we'll walk through how to predict products, avoid common mistakes, and decide when SN1 CAN'T happen.
