ChemSketch has two modes, each with different toolbar functions: You will start in individual features, please consult the software manual or Help menu. ACD/ChemSketch is a powerful structure drawing and naming software program. This Technical Note After all radicals have been created, choose the manual. Introduction to ChemSketch. ChemSketch is a free download for educational use. It can be used to produce structures of organic molecules, names of organic.

But normally you would just do all the steps sequentially on one drawing.

If you find a more recent version, please contact me, and I will update these instructions as needed. A true screen capture will include the smoothing.

This was illustrated in the section Stereochemistry: No attempt is made here to teach all of ChemSketch. Then, I made two copies of this, on the right. Alternatively, you can click the button near the right end of the second toolbar; the button looks like a model of CH 4 and lights up with the name 3D Optimization. For a new file, the two commands become equivalent; that is, using Save will bring up the Save As dialog box.

ChemSketch – An Introductory Guide

As you draw the propane structure, note the following general points Drawing of double bonds is introduced in a section below: To add a Carbon, you click on the place where you want it added. See the section Antialiasing. If you can do the things shown here, you should then be ready to pursue more features of the program on your own — as you need them.

You now have the 2D structure for ethanol Fig Fig 9, below, shows an example.

To do this, go to Tools menu, and choose 3D Structure Optimization. You’ll find that your drawings are much easier to manipulate if you learn about Grouping and Ungrouping objects in Draw mode. A new version, called 1. Add non-bonding electrons Template Organizer Reaction symbols. To do this, see the next section: Go to the Edit menu, and choose Undo 3D optimization.

You will now be returned to the main screen. It is amazing that ChemSketch is freeware because it is a quite powerful chemical chemmsketch drawing program. Similarly, Save As and Export are now equivalent. Chemistry drawing programs usually draw C atoms by default, and cnemsketch usually provide the proper number of hydrogen atoms. If you copy the image to Paint, or other graphics program, you can then save the file in the.

Save is intended for saving a new copy of an existing file, with the same name, type, and location. You can use ChemSketch to draw chemical structures, and to view them as three dimensional 3D models. The procedure for getting the names is shown below in the section Naming structures.

Repeat the process described for butane, above. ChemSketch will now switch to the 3D module, and display the molecule you have drawn. This tool is on the left tool bar — but off the screen. Many of these are file formats manyal by other programs that deal with chemical structures. Or you can choose an item from the list there, and press insert. Draw an object and finish embedding in Word. Elements in the following “organic subset” typically have well-defined valences and may be written without brackets if the number of attached hydrogens conforms to the lowest normal valence consistent with explicit bonds.


The general approach is to draw the neutral molecule first, then change the charge as needed. Drawing your first molecule D. You use the C tool — the default — for this. I am updating this page for the new version. Click it, to add it to the toolbar.


You might start by exploring and checking these topics in the Template Window: Go to Templates menu, choose Template Window. ChemSketch seems to draw the E isomer which is transby default, and it properly names it as the E isomer.

If those buttons do not appear, it means that you have not yet opened the other module. The “Copy to 3D” function does not seem to know whether you actually have a 3D structure.

ChemSketch will run fine “out of the box”. Now that you know about the role of the 3D program You can then use the image in a web page. You should now see a 2D structure of propane Fig The geometry that is shown is correct, taking into account the double bond, but the doubleness of the bond per se is not shown in some views. Be sure chemsketfh have done the 3D optimization before copying to 3D. You will get a dialog box with much to offer. Here are a few e xamples, with answers.

If you want to run ChemSketch with other systems, see Notes: Generally, the Structure mode generates structural parts of the file such as atoms and bonds and the Draw mode allows you to enhance them with arrows, boxes, and non-structure drawings.

You can open either program or both programs in any order.
