Slide Number 4

Pre-requisites

To follow this tutorial you should have knowledge of,

Basics of Chemistry upto VIII standard.

Slide Number 5

Installation

GChemPaint can be installed very easily using Ubuntu Software Center.

For more information on Ubuntu software Center,

please refer to Ubuntu Linux Tutorials on our website

Slide Number 6

About GChemPaint

What is GChemPaint?

GChemPaint is a two dimensional chemical structure editor.

It has a multiple document interface.

Slide Number 7

Uses of GChemPaint

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
Slide Number 8

Benefits of GChemPaint

GChemPaint helps in
  • Easy visualization of chemical structures
  • Converting two dimensional structures to three dimensional structures.
  • Magnification of structures
  • Automatic and manual assignment of atoms
Let's first see how to open a new GChemPaint Application.
Click on Dash home >> Search bar appears>>In the Search bar type GChemPaint

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

We can also open GChemPaint Application from Terminal.
Press CTRL+ALT+T >> open the Terminal Press CTRL, ATL and T keys simultaneously to open the Terminal.
Type GChemPaint >>press Enter to open Type GChemPaint and press Enter.

GChemPaint Application opens.

Show the Gchempaint window This is a typical GChemPaint window.
Menubar GChempaint has a standard menu-bar like other window based applications.
Point to the options as per the narration Menu bar contain menu items like File, Edit, View, Tools, Windows and Help options
Point to Toolbar, New icon, Open icon, Save icon, Print icon Toolbar contains most frequently used commands as icons.

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

Show Display area This is the Display area.

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.

Point to Statusbar Statusbar displays information about current GChemPaint activity.

It also displays contextual information about the menu items.

Now I will explain about Document Properties.
Document Properties

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

To open Document Properties window, click on File menu.

Navigate to Properties and click on it.

Document Properties window opens.

Show Document properties window Document properties window has the following fields.
Show Title Title- Let's type title of the document as “Propane”
Show Author's Name Author's Name- let's type the author's name as Madhuri.
Show Email Email– Let's leave it blank.
Show History History – This field shows the creation date of the document.

It also shows the Revision date of the document.

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

Show Theme Theme- let's leave this field as GChemPaint
Show Comments Comments- In the Comments field, we can add text related to the document.

Let's enter name of the compound and its formula

Propane CH3-CH2-CH3

Click on Close button Let's click on Close button to close the window.
Let's next learn about Toolbox.
Tool box Toolbox contains buttons for different tools.

Toolbox is displayed along with the active document window.

Draw the structures Let's now draw structures using Toolbox buttons.

Let's first draw the structure of propane.

Propane is CH3-CH2-CH3

Point to “Add Chain” tool Let's use Add a Chain tool from Tool box to draw a carbon chain.
Click on Add a Chain>> Display area Click on Add a Chain tool then on the Display area.

The Carbon chain is a drawn on the Display area.

Change orientation of Chain To change the orientation of the chain, click on the Add a Chain tool.
Display area>>click and hold the left mouse button In the Display area, click and hold the left mouse button to change the orientation.
Do not release left mouse button Do not release left mouse button until the direction of the chain is fixed.
Release the left mouse button Release the left mouse button after fixing the direction.

We see that carbon chain is drawn.

Note once we click on the Display area, chain length and orientation of the chain are fixed.
Display Atoms. Let's now display atoms on each position in the chain.

Here we have 3 positions to display atoms.

Right click on first chain position Right click on first chain position, a Submenu opens.
Select Atoms >> click on Display symbol Select Atoms then click on Display area, to display atoms at that position of the chain.
Like wise, let's display atoms at all positions of the chain.

Here the structure of “Propane” is drawn

Pentane structure Let's next draw a pentane structure on the same window.
Click on Add a Chain>> Display area Click on the Add a Chain tool, then click on the Display area.
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's 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.
