I'm a beginning chemistry/biotech student, and we are studying functional groups.
We need to memorize several basic groups, so I am seeking a basic chemical-drawing program that will let me draw molecules and functional groups.
I've looked at both MarvinSketch and ACD/ChemSketch, and both of them are almost incomprehensible to use!!
For example, I want to enter a hydroxyl group ( -OH ), can't get much simpler than that!
But when I click on O on the atoms bar of either program, then click in the workspace, they *both* insert H2O, and don't appear to give me any way to edit the group that they've inserted.
Does anyone know how to make either of these programs actually work?
Otherwise, are there any other basic compound-editing programs available?
