GChemPaint/C2/Formation-of-Bonds/English

Visual Cue	Narration
Slide Number 1 Title Slide	Hello everyone. Welcome the tutorial on Formation of bonds in GChemPaint.
Slide Number 2 Learning Objectives	In this tutorial, we will learn Add bonds to the existing bond Orient the bonds Add Stereochemical bonds Inverse wedge hashes
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 with Ethane structure.
	Let's learn to convert saturated hydrocarbon to usaturated hydrocarbons.
Point to the Ethane structure.	Let's copy Ethane structure and paste it twice on the Display area.
Click on Select one or more objects tool to select Ethane.	Click on Select one or more objects tool to select Ethane structure.
Press CTRL +C to copy the structure Press CTRL + V to paste the copied structure	Press CTRL +C to copy the structure. Press CTRL + V to paste the copied structure Observe that two structures overlap each other.
Place the cursor on the structure >>drag it with the mouse.	Let's move the second overlapping structure aside. Place the cursor on the structure and drag it with the mouse.
Point to the bonds.	Observe the single bond between the carbon atoms in the structures.
	Let's first convert the single bond to a double bond.
Click on Add a bond or change the multiplicity of existing one tool.	Click on Add a bond or change the multiplicity of existing one tool.
Click on the existing bond of the second ethane structure.	Click on the existing bond of the second Ethane structure.
Point to the structure. Point to the hydrogen atoms.	Observe that 1) Single bond is converted to a double bond. 2)Number of hydrogen atoms reduced from 6 to 4. The new structure is Ethene.
