Slide Number 2

Learning Objectives

In this tutorial, we will learn to

1. Convert Cyclohexane to Cyclohexene 2. Convert Cyclohexene to Benzene 3. Substitute Hydrogen of Benzene ring with other atoms 4. Substitute Hydrogen of Benzene ring with group of atoms 5. Merge two molecules

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.

Switch to GChemPaint application. I have opened a new GChemPaint application. Switch to GChemPaint application.
Let's first add a six membered cycle to the Display area.
Click on Add a six membered cycle tool>>Click on Display area. Click on Add a six membered cycle tool.

Click on the Display area.

Click on Add a bond or change the multiplicy of the existing one tool Click on Add a bond or change the multiplicity of the existing one tool.

Add two bonds on every corner of the cycle.

Click and drag the bonds to proper position.

Position the bonds in such a way that no two bonds touch each other.

To do so, click and drag the bonds to proper position.

Let's display carbon atoms at the corners of the cycle.
Right click on any one of the corner>>A submenu appears Right click on any one of the corner,

A submenu appears.

Select Atom >>click on Display symbol. Select Atom and then click on Display symbol.

Likewise add Carbon atoms at all corners of the cycle.

Press capital H on the keyboard. To add Hydrogen atoms to the bonds,

Press H on the keyboard.

Click on Add or modify an atom tool>>Click on all the bond positions. Click on Add or modify an atom tool

Click on all the bond positions.

Point to the Hydogen atoms. Again, see to it that no two Hydrogens overlap each other.

The obtained structure is Cyclohexane(C6H12).

Let's copy and paste the structure
Press CTRL+A to select the structure >>Press CTRL+C to copy>>Press CTRL+V and paste Press CTRL+A to select the structure.

Press CTRL+C to copy and Press CTRL+V and paste.

Point to the structure. Let's convert the second Cyclohexane structure to Cyclohexene.
Click on the Eraser tool >> delete one of the hydrogen bonds of the adjacent carbon atoms. Click on the Eraser tool.

Delete one hydrogen bond from each of the adjacent carbon atoms.

Click on Add a bond or change the multiplicity of the existing one tool>>click the bond between deleted hydrogen bonds. Click on Add a bond or change the multiplicity of the existing one tool.

Then click on the bond between deleted hydrogen bonds.

Point to the structure. A double bond is formed.

The obtained structure is Cyclohexene(C6H10)

Let's convert Cyclohexene to Cyclohexadiene and then to Benzene.

Ensure that Current element is Carbon.

Click on the Eraser tool >> delete one of the hydrogen bonds of the adjacent carbon atoms. Click on the Eraser tool.

Delete one hydrogen bond from each of the adjacent carbon atoms.

Click on Add a bond or change the multiplicity of the existing one tool Click on Add a bond or change the multiplicity of the existing one tool.

Then click on the bond between deleted hydrogen bonds.
