1.1 Properties of Water/ Hydrogen Bonding

Front

What are hydrogen bonds?

Back

Hydrogen bonds are weak attractions that occur between a hydrogen atom covalently bonded to a highly electronegative atom (like oxygen) and another electronegative atom.

Front

Are hydrogen bonds strong interactions?

Back

False. Hydrogen bonds are relatively weak compared to covalent or ionic bonds.

Front

What is the force of attraction that exists between molecules called?

Back

Intermolecular force.

Front

What process occurs when water changes from a gas to a liquid?

Back

Condensation.

Front

Does HCl have hydrogen bonding?

Back

No, HCl does not exhibit hydrogen bonding.

Front

What type of bond is formed between the negative oxygen atom of one water molecule and the positive hydrogen atom of another water molecule?

Back

Hydrogen bonds.

Front

What is the main property of water that allows it to have a high specific heat?

Back

Hydrogen bonding.

Front

What is the term for the attraction between molecules of the same substance?

Back

Cohesion.

Front

What is the term for the attraction between molecules of different substances?

Back

Adhesion.

Front

How does water's polarity affect its solvent properties?

Back

Water's polarity allows it to dissolve many ionic and polar substances, making it an excellent solvent.
