If you believe a reaction will take place, draw the structural formula for the chief organic product using the drawing window on the right. If no reaction is expected, draw the starting reactant structure.

In a few cases more than one organic product is formed. Write the formula for the major product from the reactant (on the left in the equation), ignoring byproducts from the reagents. In a few cases stereochemical configuration must be designated. Both chiral and achiral stereoisomers may be drawn, and (E/Z) isomers of appropriately substituted double bonds are recognized. Isomerism due to chiral centers is specified by the wedge/hatched bond tool. Repeated clicking on a bond alternates its orientation. Two of the bonds to a chiral center must lie in the plane of the drawing and must connect heavy atoms (not hydrogen). The remaining bond(s) should then be drawn as wedge and hatched lines (do not draw bonds to hydrogen.
