Polar and Nonpolar Molecules

Why is it difficult to wash oil from your hands with plain water?

• Both substances are polar. Like polarities repel.

• Both substances are nonpolar. Like polarities repel.

• Water is nonpolar, and oil is polar, so they will not combine.

• Water is polar, and oil is nonpolar, so they will not combine.

Why is the molecule nonpolar?

• There are nonbonding pairs on the central atom.

• There are different types of elements bonded to the central atom.

• There are no nonbonding pairs on the central atom and all of the atoms bonded to the central atom are the same.

Is the following molecule polar or nonpolar?

• polar

• nonpolar

In order to determine if a molecule is polar, you must consider the

• polarity of bonds and symmetry of the molecule.

• number of electrons and number of bonds.

• polarity of bonds only.

• total charge of each ion and number of multiple bonds.

To which term of reference does the following description refer to?"an unequal distribution of an electrical charge"

• Polar

• Nonpolar

• Both

Answer explanation

The unequal distribution "or sharing" of electrons results in - one side of a Polar Covalent Bond being partially negative while the other side is partially positive.

Attractions between polar molecules are stronger than attractions between nonpolar molecules.

• true

• false

Why is the molecule polar?

• There are nonbonding pairs on the central atom.

• There are different types of elements bonded to the central atom.

• There are no nonbonding pairs on the central atom and all of the atoms bonded to the central atom are the same.
