Honors WS 3.10: Lewis Structures; VSEPR Hybridization - Polarity Remix Directions 1st time around: (1) Draw the Lewis Structure. (2) Determine the molecular Geometry and then write it in the 1" box below. (3)

Redraw the Lewis structure to make it look as close as possible to the molecular shape using dashes and wedges if necessary. (4) Give the orbital

hybridization for the central atom in upper right corner of the box.

Directions 2"d time around: (1) Assign partial positive and partial negative charges to all bonds that have them. (2) Determine if the molecule is

polar or non-polar in the 2"d box below. (3) In the case of polar molecules, draw the dipole moment.
