Molecular Polarity

Q. In the PhET simulation window, click the Three atoms option. Drag the switch to "on" under Electric Field. Vary the shape and electronegativity of each atom to observe the effect of the electric field. After experimenting with the PhET, draw a molecule of dibromomethane (CH2Br2). Use this drawing to assign partial charges and determine whether or not the molecule is polar. The positive plate is on the right, and the negative plate is on the left. An electric field is set up between the plates. The molecule will orient according to the electric field to minimize charge distribution. Complete the diagram showing how dibromomethane (CH2Br2) will orient itself in an electric field according to partial positive and negative charges. Drag the appropriate labels to their respective targets.
