Changing an Atom to a Chemical Group

This can be done in several ways, including:

 

•	In DRAW or EDIT mode, right-click on an atom, select Element and then Chemical Groups, and then pick the desired group from the subsequent pull-down menus.

•	In DRAW or EDIT mode, select Atoms from the top-level menu, then hit Element followed by Chemical Groups, and pick the group you want from the subsequent menus. You will then be asked to pick the atom(s) which are to be replaced by the group.

•	Select the atoms which you want to replace. Then hit Atoms in the top-level menu, followed by Element and Chemical Groups in the resulting pull-down menus, and then pick the group you require.

•	In DRAW mode, change the current element type to a chemical group by hitting the Groups... button at the bottom of the window and selecting the required group from the subsequent menus. Then left-click on the atom(s) you wish to replace.

•	A complete list of groups can be obtained by selecting the View... option, which appears in the menu that is displayed whenever a Chemical Groups or Groups... button is hit. Groups may be selected from the resulting dialogue box and added to the query substructure.

•	The program will not prevent you from changing a non-terminal atom to a chemical group, but it will never make chemical sense to do so, as a group only has one point of attachment.
