C0 — Water

Question 1

Hydrophilic

Answer 1

Solutes that have an affinity for water and therefore dissolve readily in it.

Examples include polar molecules, ions, and charged molecules.

Question 2

Hydrophobic

Answer 2

Molecules that are not very soluble in water, such as lipids and some proteins found in biological membranes. These molecules are non-polar and cannot form hydrogen bonds with water.

Question 3

Amphipathic

Answer 3

Molecules that have both hydrophobic and hydrophilic regions on the same molecule.

Question 4

Bonding in and between water molecules

Answer 4

2 Hydrogen atoms in water covalently bonded to one oxygen atom at 104.5 degree angle.

Between water molecules: hydrogen bonds
Between atoms within water molecules: covalent bonds
