Using the program Bondit
Bondit is a program designed to provide practice for students
taking introductory high school, Advanced Placement, or college
level general chemistry. Organic compounds can also be done including
some ring compounds. The intent is to provide the student with practice
in drawing Lewis dot formulas that follow the octet rule. A
3-dimensional representation can also be seen after the structural
formula has been completed. Molecules and structures can be created,
saved to the clipboard, and then copied into any other Windows
application.
Two predesigned sets of compounds are included with the
registered copy which can be used as classroom exercises. A text file
is included with the registered version called ORGANIC.LAB which will
provide the student with a number of organic compounds.
Compounds up to 26 atoms in size can be created with the program.
The unregistered version of the program can only do compounds
containing H, S, O, and benzene. The registered copy can do compounds
containing any combination of the atoms listed on the left of the
screen when the program is running. To obtain a registered copy
of bondit see the file register.txt. Bondit 2.65 is designed for
Windows 95 and Windows NT.
Installing bondit on you hard drive.
Start windows and place the disk with the bondit files in your
disk drive. Click on File|Run in the upper left hand corner of program
manager. The name of the program to be run is A:install. If the files
are on directory C:\temp then enter c:\temp\install. The files
will be installed onto your hard drive and a program group created for
bondit including icons for some of the bondit files.
Using bondit
The goal of bondit is to draw an electron dot representation
(Lewis formula) of molecules which follow the octet rule. To
choose an atom click the appropriate symbol on the left of the
screen. The atom chosen will appear on the right. The atom may
be moved by placing the mouse cursor over it, clicking the left
mouse button, and dragging the atom to the area desired. To bond
one atom to another select a single atom by using the mouse and
move it so that it is placed above the atom with which you wish to
bond. Releasing the mouse button will bond the two atoms together
if possible. An atom cannot exceed 8 electrons (a single bond
counts as 2) except hydrogen which cannot exceed 2 electrons.
Multiple bonds may be made by clicking the right mouse button over
the existing bond you want to make a multiple bond. If there are
too many or not enough electrons for bonding a multiple bond will
not form. Cations and anions can be made by choosing the Edit|Add
Electron or Edit|Subtract Electron option.
Click on 3-D model to see a three-dimensional representation
of a completed molecule. Pressing the "End" key will accomplish
the same thing. The molecule may be rotated using the arrow keys
or moved using the shift and arrow keys. Press "Home" to return.
Molecule Menu Items:
New
This menu item will start a new molecule. You will be asked
if you want to save the molecule you were working on previously.
Open
This menu item will open a previously saved molecule. Use the
mouse or keyboard to select the file of interest. Files can also
be deleted by choosing delete after selecting the desired file.
Save
To save a molecule choose this option. If the molecule
already has a name the new state of the molecule will replace the
former state. If the molecule does not have a name you will be
asked for one. Use a single word with no spaces of 8 letters or
less.
SaveAs
To save a molecule under a different name while retaining the
molecule with the former name use this option. You will be asked
for a filename. Use a single word with no spaces of 8 letters or
less.
Exit
This command will terminate the program.
Edit Menu
Undo
Choose this menu item to return to the state of the molecule
before your previous procedure.
Add Electron
To add an electron to an atom choose this menu item and then
click the right mouse button on the atom which is to gain the
electron.
Subtract Electron
To subtract an electron from an atom choose this menu item and
then click the right mouse button on the atom which is to lose the
electron.
Abbreviate H's
Occasionally you may wish to abbreviate a molecule so
that you may bond other atoms. To do so click on this menu item.
All H atoms will be abbreviated.
Copy to Clipboard
To copy a molecule or structure to the clipboard choose
Edit|Copy to Clipboard when viewing the molecule or Copy to
Clipboard if viewing the structure. The molecule or structure
will be copied to the clipboard. To transfer the molecule or
structure to another application start the application and choose
Edit|Paste. The molecule or structure will be copied to your
application and you can change it as you would any object added.
Practice Menu
Click on Start Lab or Organic Chemistry to do a series of
preloaded molecules. A new menu bar will appear. To start the
same molecule again choose the Repeat menu item. To go on to the
next molecule click on the Next menu item. A completed molecule
may be seen in three-dimensions by clicking on View|3-D model.
You may Quit at any time by choosing Practice|Quit (returns to the
regular program) or by choosing Molecules|Exit (terminates the
program). The Organic item will not function in the unregistered
version.
