Slide Number 1

Title Slide

Hello everyone

Welcome the tutorial on Formation of molecules in GChemPaint.

Slide Number 2

Learning Objectives

In this tutorial, we will learn to
  • Add and modify structure of compounds
  • Change current element
  • Add Alkyl groups
  • Add and modify carbon chain
Slide Number 3

System Requirement

Here I am using

Ubuntu Linux OS version. 12.04

GChemPaint version 0.12.10

Slide Number 4

Pre-requisites

To follow this tutorial you should be familiar with,

GChemPaint chemical structure editor.

If not, for relevant tutorials, please visit our website.

Slide Number 5

Structures

Here is slide for the structures of Propane, Butane and Heptane.
Switch to GChemPaint application. I have opened a new GChemPaint application with Propane and Butane structures as shown in the slide.
Point to Carbon atoms. Let's replace the terminal Carbon atoms in Butane structure with Chlorine atoms.
Point to Periodic table combo button. For this I will use Periodic table combo button.
Click on the Current element drop-down arrow button.

Hover the mouse over the Periodic tab le

Click on the Current element drop-down arrow button.

This button is known as Periodic table combo button.

Observe the built-in Modern periodic table.

Click on Cl from the table.

Point to the Cl in toolbox

Click on Cl from the table.

Observe Cl in the tool box.

Click on Add or modify an atom tool>>click to replace

Point to the structure

Click on Add or modify an atom tool.

Click on the terminal atoms to replace them with Cl atoms.

The new structure obtained is 1,2-Dichloroethane.

Let's write its name below the structure.
Click on Add or modify a text tool>>Click on Display area Click on Add or modify a text tool.

Text tool's property page opens.

Click on the Display area below the structure.

Point to the blinking cursor You can see the blinking cursor enclosed in a green box.

Type 1,2-Dichloroethane in the box .

Click on "Select one or more objects" tool>>To close the text tool's property page. Click on Select one or more objects tool, to close the text tool's property page.
Next let's replace the central Carbon atom in Propane structure with Oxygen atom.
Press Shift and O keys simultaneously>> A Sub-menu opens with O and Os Place the cursor near the central atom of the Propane structure.

Press capital O.

A Sub-menu with O and Os opens.

Select O. Select O.

Carbon and Hydrogen atoms will be replaced by Oxygen atom.

The new structure obtained is Dimethylether.

Let's write its name below the structure.
Click on Add or modify a text tool>>Click on Display area Click on Add or modify a text tool.

Click on the Display area below the structure.

Point to the blinking cusor Type Dimethylether in the box.
Let's save the file now.
Click on Save the current file icon on the toolbar Click on Save the current file icon on the toolbar
Save as dialog box opens Save as dialog box opens.
Enter the file name as Chloroethane-ether >> click on Save button. Enter the file name as Chloroethane-ether.

Click on Save button.

Click on Close to close the window. Let's Click on Close to close the window.
Slide Number 5

Assignment

Here is an assignment

Draw 'Ethane and Pentane structures.

Replace one Carbon atom of Ethane with Br.

Replace the terminal Carbon atoms of Pentane with I.

Your completed assignment should look like this.

Now I will explain about Alkyl groups.
Slide Number 6

Alkyl groups

Alkyl group is a fragment of Alkane.

For example: Methyl CH3 is a fragment of Methane CH4

Successive members of an Alkyl group differ by a CH2 group.

Homologues of the Alkyl group series include,

Methyl CH3

Ethyl C2H5

Propyl C3H7

Butyl C4H9 and so on.

Switch to GChemPaint application. I have opened a new GChemPaint application with Heptane structure.
Now I will demonstrate how to number the carbon chain positions.

Numbering helps to identify the chain positions.

Click on Add or modify a text tool>> Click on Display area near the first chain position>>

Enter 1 in the green box.

Click on Add or modify a text tool.

Click on the Display area near the first chain position.

Enter 1 in the green box.

Click near the second chain position>> Enter 2 in the box. Next, click near the second chain position.

Enter 2 in the box.

Point to other chain positions. Likewise I will number the other chain positions as 3, 4, 5, 6 and 7.
Now let's branch Heptane using Alkyl groups at various positions.
Point to the third position. Let's add a Methyl group to the third position.
Click on Add a bond or change the multiplicity of existing one tool >> click on the position. Click on Add a bond or change the multiplicity of existing one tool.

Click on the position.

Observe the change in the atoms. <Pause>

Click on Add a chain tool.

Click on the position.

Let's add an Ethyl group on the fifth position.

Click on Add a chain tool.

Click on the position.

Next I will display atoms on all positions.
Right click on the position>> A Submenu opens>>Select Atom>> click on

Display symbol.

Right-click on the position.

A Submenu opens

Select Atom and then click on Display symbol.

Likewise I will display atoms at other positions.

Let's see how many times we can branch at one position.
Click on Add a bond or change the multiplicity of existing one tool.
