|-
|00:01
|Hello everyone

|-
|00:02
|Welcome the tutorial on '''Formation of molecules''' in '''GChemPaint.'''

|-
|00:08
|In this tutorial, we will learn to

|-
|00:11
|* Add and modify structure of compounds

|-
|00:14
|* Change current element

|-
|00:16
|* Add Alkyl groups

|-
|00:18
|* Add and modify carbon chain

|-
|00:21
|Here I am using '''Ubuntu Linux''' OS version. 12.04 '''GChemPaint''' version 0.12.10

|-
|00:33
|To follow this tutorial you should be familiar with,

|-
|00:38
|'''GChemPaint''' chemical structure editor.

|-
|00:41
|If not, for relevant tutorials, please visit our website.

|-
|00:47
|Here is slide for the structures of '''Propane, Butane''' and '''Heptane'''.

|-
|00:54
|I have opened a new '''GChemPaint''' application with '''Propane''' and '''Butane''' structures as shown in the slide.

|-
|01:03
|Let's replace the terminal '''Carbon''' atoms in '''Butane''' structure with '''Chlorine''' atoms.

|-
|01:10
|For this I will use '''Periodic table combo''' button.

|-
|01:15
|Click on the '''Current element''' drop-down arrow button.

|-
|01:19
|This button is known as '''Periodic table combo''' button.

|-
|01:23
|Observe the built-in '''Modern periodic table'''.

|-
|01:27
|Click on '''Cl''' from the table.

|-
|01:30
|Observe '''Cl''' in the tool box.

|-
|01:33
|Click on '''Add or modify an atom''' tool.

|-
|01:37
|Click on the terminal atoms to replace them with '''Cl''' atoms.

|-
|01:43
|The new structure obtained is '''1,2-Dichloroethane'''.

|-
|01:48
|Let's write its name below the structure.

|-
|01:52
|Click on '''Add or modify a text''' tool.

|-
|01:56
|Text tool's property page opens.

|-
|01:59
|Click on the '''Display area''' below the structure.

|-
|02:03
|You can see the blinking cursor enclosed in a green box.

|-
|02:08
|Type '''1,2-Dichloroethane''' in the box .

|-
|02:14
|Click on '''Select one or more objects''' tool, to close the text tool's property page.

|-
|02:21
|Next let's replace the central '''Carbon''' atom in '''Propane''' structure with '''Oxygen''' atom.

|-
|02:28
|Place the cursor near the central atom of the '''Propane''' structure.

|-
|02:33
|Press capital '''O'''.

|-
|02:35
|A '''Sub-menu''' with '''O''' and '''Os''' opens.

|-
|02:39
|Select '''O'''.

|-
|02:40
|'''Carbon''' and '''Hydrogen''' atoms will be replaced by '''Oxygen''' atom.

|-
|02:46
|The new structure obtained is '''Dimethylether.'''

|-
|02:51
|Let's write its name below the structure.

|-
|02:54
|Click on '''Add or modify a text''' tool.

|-
|02:58
|Click on the '''Display area''' below the structure.

|-
|03:01
|Type '''Dimethylether''' in the box.

|-
|03:06
|Let's save the file now.

|-
|03:08
|Click on '''Save the current file''' icon on the toolbar

|-
|03:12
|'''Save as''' dialog box opens.

|-
|03:15
|Enter the file name as '''Chloroethane-ether'''.

|-
|03:20
|Click on '''Save''' button.

|-
|03:23
|Let's Click on '''Close''' button to close the window.

|-
|03:27
|Here is an assignment

|-
|03:29
|Draw ''''Ethane''' and '''Pentane''' structures.

|-
|03:32
|Replace one '''Carbon''' atom of '''Ethane''' with '''Br'''.

|-
|03:36
|Replace the terminal '''Carbon''' atoms of '''Pentane''' with '''I'''.

|-
|03:41
|Your completed assignment should look like this.

|-
|03:45
|Now I will explain about '''Alkyl groups'''.

|-
|03:49
|'''Alkyl group''' is a fragment of '''Alkane'''.

|-
|03:53
|For example: '''Methyl CH3''' is a fragment of '''Methane CH4'''

|-
|04:00
|Successive members of an '''Alkyl group''' differ by a ''' CH2''' group.

|-
|04:06
|Homologues of the '''Alkyl group''' series include,

|-
|04:10
|'''Methyl CH3'''

|-
|04:15
|'''Ethyl C2H5'''

|-
|04:20
|'''Propyl C3H7'''

|-
|04:23
|'''Butyl C4H9''' and so on.

|-
|04:29
|I have opened a new '''GChemPaint''' application with '''Heptane''' structure.

|-
|04:35
|Now I will demonstrate how to number the carbon '''chain''' positions.

|-
|04:40
|Numbering helps to identify the '''chain''' positions.

|-
|04:44
|Click on '''Add or modify a text''' tool.

|-
|04:48
|Click on the '''Display area''' near the first chain position.

|-
|04:52
|Enter 1 in the green box.

|-
|04:55
|Next, click near the second chain position.

|-
|04:59
|Enter 2 in the box.

|-
|05:02
|Likewise I will number the other chain positions as 3, 4, 5, 6 and 7.

|-
|05:13
|Now let's branch '''Heptane''' using '''Alkyl groups''' at various positions.

|-
|05:19
|Let us add a '''Methyl group''' to the third position.

|-
|05:24
|Click on '''Add a bond or change the multiplicity of existing one''' tool.

|-
|05:30
|Click on the position.

|-
|05:32
|Observe the change in the atoms.<Pause>

|-
|05:36
|Let us add an ''' Ethyl group''' on the fifth position.

|-
|05:40
|Click on '''Add a chain''' tool.

|-
|05:43
|Click on the position.

|-
|05:46
|Next I will display atoms on all positions.

|-
|05:51
|Right-click on the position.

|-
|05:53
|A '''Submenu''' opens

|-
|05:55
|Select '''Atom''' and then click on '''Display symbol'''.

|-
|05:59
|Likewise I will display atoms at other positions.

|-
|06:06
|Let's see how many times we can branch at one position.

|-
|06:12
|Click on '''Add a bond or change the multiplicity of existing one''' tool.

|-
|06:18
|Click on the fourth position.

|-
|06:21
|Click again.

|-
|06:23
|Observe the branching in the '''Carbon''' chain.

|-
|06:27
|Try to click for the third time.

|-
|06:30
|We do not see the branching.

|-
|06:33
|Note that branching is possible only twice at each position.

|-
|06:39
|This is because it satisfies '''Carbon's tetra valency'''.

|-
|06:43
|To save the file, Press '''CTRL+ S.'''

|-
|06:47
|'''Save as dialog box,''' opens.

|-
|06:50
|Enter the file name as '''Alkyl Groups'''.

|-
|06:53
|Click on ''' Save''' button.<PAUSE>

|-
|06:57
|Let's Summarize what we have learnt.

|-
|07:00
