OZ.7

Question 1

What is the strongest type of intermolecular bond?

Answer 1

Hydrogen bonding.

Question 2

Hydrogen bonding is essentially a special case of which type of dipole intermolecular bond?

Answer 2

Permanent dipole - permanent dipole.

Question 3

What are three examples of extreme polar bonds with hydrogen in order for hydrogen bonding to occur?

Answer 3

• H-F
• H-O
• H-N

Question 4

What lines up the hydrogen bond?

Answer 4

A lone pair of electrons on the oxygen, nitrogen or fluorine, lining up with a hydrogen atom.

Question 5

Why is hydrogen bonding in water so strong?

Answer 5

The oxygen has two pairs of lone pair, and there two hydrogen atoms per oxygen therefore allow a lot attraction between O and H.

Question 6

What is viscosity?

Answer 6

The measure of how easily a liquid flows.

Question 7

How is the viscosity of liquid that contains hydrogen bonding?

Answer 7

High viscosity.

Question 8

How is the solubility of substances that contains hydrogen bonding in water?

Answer 8

Substance with hydrogen bonding are often soluble in water as hydrogen bonds can be formed with water molecules to help with the dissolving process.
