Specifying a Substance by Functional Group

Instead of drawing a specific structure, you can represent a reactant, reagent, or product by a functional group term (e.g., Acyclic Ketone).

1. Click the Functional Group    icon. The Functional Groups dialog box appears.

2. Click a functional group class to expand it.

Select the class term (e.g., ALKYNES) or select a specific term (e.g., pi-Alkyne).

Alternatively, you can start typing the functional group term into the text box. When you have entered at least three characters, the Structure Editor will display matching terms.

3. Click the functional group term to select it.

4. Click the drawing area to place the term.

5. Specify the reaction role for the term by drawing a reaction arrow or by clicking the Reaction Role    icon.
