IONIC, POLAR AND NON POLAR COVALENT BONDS

Which of these compounds will not dissolve at all in water?

• CCl₄

• CS₂

• NH₃

• both NH₃ and CS₂

• soap

Answer explanation

Sucrose is polar covalent so it is polar like water, KCl and CaCl₂ are ionic so they will dissolve but hexane in non polar covalent and will not dissolve.

What type of bond is the O-H in ethanol?

• ionic

• metallic

• polar covalent

• non polar covalent

Answer explanation

C₂H₆O, is made of only nonmetals. This makes it one of the two covalent types.

What does the term soluble mean?

• Can dissolve into something else

• Can not dissolve into something else

• Able to be solved

• A property that describes how well a substance transmits electricity.

What kind of bonding is represented by this picture?

• Ionic

• non polar covalent

• polar covalent

• Network Covalent

Answer explanation

Remember in an ionic bond ions are surrounded by ions with opposite charges to form a crystal lattice.

What type of bonding is found in ammonia, NH₃(s)?

• Ionic

• Metallic

• covalent

• a James Bond

Answer explanation

NH₃(s) is only made of nonmetals. That makes it covalent. Because it doesn't contain only C, Si, or a combination of Si and O we know that it's only a molecular covalent compound.

Elements on the LEFT side of the periodic table will most likely form:

• Positive ions

• Negative ions

• Neutral Ions

• None of these

Answer explanation

Remember that metal atoms, which make up most of the left hand side of the periodic table, tend to form positive ions (cations).

Which type of bond has an equal sharing of electrons?

• Iconic

• non polar covalent

• Ionic

• polar covalent

Answer explanation

In a nonpolar covalent bond the electrons are shared equallly between nonmetals.

Ionic bonds are between _______ and ________.

• nonmetals and nonmetals

• metals and metals

• metals and nonmetals

• none of these options

Answer explanation

Remember to review the different types of bonds and their properties.
