Molecular Polarity Quiz

What is the first step in determining if a molecule is polar using the traditional method?

• Draw the Lewis structure

• Check for lone pairs on the central atom

• Identify the terminal atoms

• Measure the bond angles

According to the simplified method, when is a molecule considered polar?

• When all bonds are nonpolar

• When it has no lone pairs

• When it has different terminal atoms or lone pairs on the central atom

• When it has a symmetrical shape

In the molecule CF4, why is it considered nonpolar?

• It has lone pairs on the central atom

• It has different terminal atoms

• It has the same terminal atoms and no lone pairs on the central atom

• It has a bent shape

What makes HCN a polar molecule?

• It has a symmetrical shape

• It has different terminal atoms

• It has no lone pairs

• It has the same terminal atoms

Why is NF3 considered a polar molecule?

• It has lone pairs on the central atom

• It has no lone pairs

• It has different terminal atoms

• It has a linear shape
