Time	Narration
00:01	નમસ્તે મિત્રો,
00:02	GChemPaint. માં અણુની રચના પરનાં આ ટ્યુટોરીયલમાં સ્વાગત છે.
00:08	આ ટ્યુટોરીયલમાં, આપણે આપેલ વિશે શીખીશું,
00:11	*
00:14	* વર્તમાન એલિમેન્ટ બદલાતા
00:16	* Add Alkyl groups ઉમેરતા
00:18	* carbon chain ને ઉમેરો અને ફેરફાર કરતા .
00:21	અહી હું વાપરી રહ્યી છું: Ubuntu Linux OS આવૃત્તિ. 12.04 GChemPaint આવૃત્તિ 0.12.10
00:33	આ ટ્યુટોરીયલનાં અનુસરણ માટે તમે પરિચિત હોવા જોઈએ ,
00:38	GChemPaint કેમિકલ સ્ટ્રક્ચર એડિટર.
00:41 જો નથી , સંદર્ભિત ટ્યુટોરીયલો માટે, કૃપા કરી અમારી વેબસાઈટની મુલાકાત લો.
00:47	અહી સ્ટ્રક્ચરોની સ્લાઈડ છે Propane, Butane અને Heptane.
00:54	સ્લાઈડ માં બતાવ્યા પ્રમાણે Propane અને Butane સ્ટ્રક્ચર સાથે મેં નવું GChemPaint એપ્લીકેશન ખોલ્યું છે.
01:03	ચાલો ટર્મિનલ Carbon પરમાણું ને Butane સ્ટ્રક્ચરમાં Chlorine પરમાણું સાથે બદલીશું.
01:10	આ માટે હું Periodic table combo બટન નો ઉપયોગ કરીશ.
01:15	Current element ડ્રોપ-ડાઉન એરો બટન પર ક્લિક કરો.
01:19	આ બટન ને Periodic table combo બટન કહેવાય છે.
01:23	Modern periodic table આંતરિકની નોંધ લો.
01:27	ટેબલ પરથી Cl પર ક્લિક કરો.
01:30	ટૂલ બોક્ક્ષમાં Cl ની નોંધ લો.
01:33	Add or modify an atom ટૂલ પર ક્લિક કરો.
01:37	Clorine (Cl) પરમાણું ને બદલવા માટે ટર્મિનલ પરમાણું પર ક્લિક કરો.
01:43	નવું સ્ટ્રક્ચર મેળવ્યું છે તે છે 1,2-Dichloroethane.
01:48	ચાલો સ્ટ્રક્ચરની નીચે તેનું નામ લખીએ.
01:52	Add or modify a text ટૂલ પર ક્લિક કરો.
01:56	ટેક્સ્ટ ટૂલ્સ પ્રોપર્ટી પેજ ખુલે છે.
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 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.
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.
06:57	Let's Summarize what we have learnt.
07:00	In this tutorial we have learnt to,
07:03	* Add and modify structure of compounds
07:07	* Change current element
07:09	* Add Alkyl groups
07:12	* Add and modify carbon chain
07:15	As an assignment,
07:16	Draw Octane structure .
07:18	Add Propyl and Butyl groups at the fourth and fifth positions of the chain.
07:25	Your completed assignment should look like this.
