Polar vs Nonpolar Using Lewis Structures

Look at this covalent molecule as a whole. What type of molecule is it? (Is it symmetrical?)

• Polar

• Nonpolar

• Ionic

The electrons in a NONPOLAR covalent molecule are shared...

• Evenly

• Unevenly

• Electrons are not shared

Partial charges are present in which type of bond(s)?

• Ionic

• Nonpolar Covalent

• Polar Covalent

• Both Polar Covalent and Ionic

• All covalent

In this Lewis structure, the symbol above F means...

• electrons are being transferred to Fluorine

• electrons are less attracted to F than H

• electrons are more attracted to F than H

• Fluorine has formed an anion

Look at this covalent molecule as a whole. What type of molecule is it? (Is it symmetrical?)

• Polar

• Nonpolar

• Ionic

Which of the following molecules is polar based on its Lewis structure?

What is the main difference between polar and nonpolar molecules when analyzing their Lewis structures?

• Polar molecules have equal sharing of electrons, nonpolar do not.

• Polar molecules have an uneven distribution of electrons, nonpolar have an even distribution.

• Polar molecules have more electrons than nonpolar molecules.

• Polar molecules are always larger than nonpolar molecules.

Which of the following statements is true about the Lewis structure of a nonpolar molecule?

• It has a symmetrical shape.

• It has an asymmetrical shape.

• It contains a lone pair of electrons.

• It has a net dipole moment.

How does the presence of lone pairs affect the polarity of a molecule in its Lewis structure?

• Lone pairs always make a molecule nonpolar.

• Lone pairs can create an asymmetrical shape, leading to polarity.

• Lone pairs have no effect on molecular polarity.

• Lone pairs make a molecule larger.

Which molecule's Lewis structure would show a polar bond?
