About GChemPaint What is GChemPaint?

GChemPaint is a two dimensional chemical structure editor. It has a multiple document interface.

• GChemPaint allows you to
• Draw and display two dimensional chemical structures.
• Drag and drop of templates
• Change length, angle and width of the bonds
• Use Chemical Calculator to calculate molecular weight of the compound

Benefits of GChemPaint

• Easy visualization of chemical and molecular structures
• Converting two dimensional structures to three dimensional structures.
• Magnification of structures
• Automatic and manual assignment of atoms

Click on Dash home. Search bar appears. In the Search bar, type GChemPaint

Click on the GChemPaint application

Type GChemPaint >>press Enter to open Type GChemPaint and press Enter.

GChemPaint Application opens.

There are icons to open a New file, Open existing file, Save a file and Print a file.

Display area shows the structures and the contents of the file that we draw and edit.

We can drag and drop tools from toolbox into the display area.

It also displays contextual information about the menu items.

Click on File menu>>Navigate to Properties>>Click on Document Properties

Navigate to Properties and click on it. Document Properties opens.

It also shows the Revision date of the document. This means, it also shows the next edited dated of the document.

Let's enter name of the compound and its formula propane CH3-CH2-CH3

Toolbox is displayed along with the active document window.

Let's first draw the structure of propane. Propane is CH3-CH2-CH3

The Carbon chain is a drawn on the display area.

We see that carbon chain is drawn.

Here we have 3 positions to display atoms.

Here the structure of “Propane” is drawn

hold the left mouse button and drag the cursor. To increase the chain length, hold the left mouse button and drag the cursor. Change orientation >>release the left mouse button Change orientation in the desired direction and release the left mouse button.

Let's display atoms on all positions. Here we have 5 positions to display the atoms.

To display atoms on first position, right click on the position.

Click on Atoms>> Display symbols A submenu opens

Select Atoms click on Display symbols to display the atoms at that position

Like wise I will display atoms at all positions. Here the structure of pentane is drawn. Click on File>> Save As Let now save the file. Go to File Menu select Save as .

Save As dialog box opens. Click on File type drop down For File type, click on the drop down arrow. Various save formats are seen. Select 2D Chemical structure Select 2D Chemical structure In filename type propane.gchempaint>> click Save Type the file name as propane.gchempaint click on Save button. File is saved with .gchempaint extension.

With this, we have come to the end of this tutorial. Let's summarise. Slide Number 9 Summary In this tutorial we have learnt, About GChemPaint Uses and Benefits Installation Open a new file Menubar, Toolbar and Status bar We have also learnt Display area Document Properties Using tool box Save the drawing with extension .gchempaint Slide Number 10 Assignment As an assignment I would like you to Draw structures of n-hexane and n-octane Change the orientation Display atoms on each position

Output of assignment should look like this.
