Substitution and Elimination Reactions
Draw the Main Product
Select a lone pair or bond, then click or drag to its destination.
Use Wedge or Dashed to click an existing bond, or click two points or drag to draw a new stereochemical bond. Click the same bond again to reverse its taper. The narrow end belongs at the stereocentre. Draw only the organic product. Counterions and by-products appear automatically once it is correct.
Drawing help and shortcuts
Click two points or drag to add bonds. Atom tools replace an existing atom or add one in empty space. Carbon hydrogens are implicit; use H to draw one explicitly when helpful for stereochemistry. Use the circled + or − tools to add or remove charges. Click or drag with Eraser to erase. Escape cancels a bond. Ctrl/⌘ Z undoes; Ctrl/⌘ Shift Z redoes. With Move, drag an atom or Shift-drag a whole connected structure. Rotating a drawing preserves its configuration; reflecting it changes its configuration unless the wedges and dashed bonds are also inverted.
