For each bond, select the arrow that indicates the direction of bond polarity.

A series of anions is shown below:

The anion on the far right is called 'BARF' by chemists, as its common abbreviation sounds similar to this word. (b) What is the electron-domain geometry around the central B in BARF?

At least two different numbers of electron groups can result in a linear molecule. What are they?

How does adding a lone pair affect the position of existing atoms and lone pairs?

Draw the Lewis structure of HCN and then determine its electron domain and molecular geometries.

In the PF₅ molecule, what is the geometry of the bond dipole for one PF bond?

Molecule with 3 atoms bonded to a central atom with 2 unshared pairs of electrons, such as CIF₃

What is the electron geometry around the phosphorus atom in phosphorus pentachloride, PCl₅?

A molecule with the formula AB2 has a linear geometry. How many electron groups are on the central atom?
