Bonding and Intermolecular Bonding

In which situation would you find intermolecular bonding?

• Ionic substances

• Covalent molecular substances

• Covalent networks

• All substances have intermolecular bonds

Which type of bonding is the strongest?

• Covalent

• Hydrogen bonding

• Dispersion forces

• Dipole-dipole bonds

In which situation would you find intermolecular bonding?

• Water

• SiO₂

• NaCl

• Copper

Which type of bonding is the weakest, if all other factors remain equal?

• Covalent

• Hydrogen bonding

• Dispersion forces

• Dipole-dipole bonds

What type of intermolecular bonding occurs in water?

• H-bonding only

• H-bonding

  Dipole- dipole bonding only

• H-bonding,

  dipole-dipole

  and dispersion forces

• H-bonding and dispersion forces only

Which types of bonds do not have directional bonds?

• Metallic

• Ionic

• Covalent Networks

• Covalent molecules

Which statement is not true about directional bonds?

• They are rigid

• They are created by electrostatic forces

• They cause brittleness

• They can be relatively weak bonds

Answer explanation

All bonds are caused by electrostatic forces.

All directional bonds cause a substance to be brittle

Directional bonds are either ionic or covalent and these are very strong bonds that are hard to break.

Which statement about NaCl is untrue?

• Contains directional bonds

• Contains bonds that are stronger than covalent molecular bonds

• Is a brittle substance

• Has a high melting and boiling point due to strong bonds

The following model represents...

• A covalent network

• Ionic bonding

• Metallic bonding

• A covalent molecular substance

What do A and B respresent?

• A = + metal cation

  B = - non-metal anion

• A = + metal cation

  B = delocalised electron

• A = + metal cation

  B = inner orbital electrons
