IMF simulation - Christina Hicks | Library

Shown below is a simulation that will allow exploration of polarity.
Take a few minutes to explore what you can change and view in this simulation.

1

Match the color of the atoms to the element they represent

Draggable item		Corresponding Item
Black		Carbon
Red		Hydrogen
Green		Fluorine
Blue		Oxygen
White		Nitrogen

1

What do the colors on the "molecular surface" correspond to?

Draggable item		Corresponding Item
Red		No charge (neutral)
Gray/white		Positive
Blue		Negative

1

Reset the simulation. Which elements are shown in the molecule before any changes are made?

1

Before any changes are made, the molecule is nonpolar.

Replace a hydrogen atom with Fluorine. (Try different locations for the F). View the molecular surface to look for partially charged areas of the molecule.

1

Replacing a H with F (in any location) results in a polar molecule.

Replace 2 different hydrogen atoms with Fluorines- try different locations.  View the molecular surface to look for partially charged areas of the molecule.

1

Replacing 2 Hs with Fs (in any location) results in a polar molecule.

1

Replace Hs with the other elements. What results do you find?

Contains C & H only
Contains C, H and O
Contains C, H and F
Contains C, H and N
Contains C and F only (replace all Hs)

Polar
Non polar

1

Try replacing the central carbons with nitrogen and oxygen. Do you create polar or nonpolar molecules?
