Molecular Geometry and Bonding in OF2

The video tutorial explains how to draw the Lewis structure for Oxygen difluoride (OF2). It begins by calculating the total number of valence electrons using the periodic table, identifying oxygen and fluorine's valence electrons. The tutorial then guides placing the least electronegative element, oxygen, in the center and forming covalent bonds with fluorine atoms. It ensures the completion of octets for all atoms and discusses the bent molecular geometry due to lone pairs on oxygen. The video concludes with a summary of the completed Lewis structure.

How many valence electrons are used to complete the octets of the fluorine atoms in OF2?

• 20

• 8

• 12

• 16

After completing the octets, how many valence electrons are left to place on the oxygen atom in OF2?

• 2

• 4

• 6

• 8

What is the molecular geometry of OF2?

• Bent

• Linear

• Tetrahedral
