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.

Match the color of the atoms to the element they represent

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

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

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

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

Before any changes are made, the molecule is nonpolar.

True

False

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.

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

True

False

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

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

True

False

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)
