Solubility

Question 1

What is water solubility mean?

Answer 1

an effective solvent as it can form hydrogen bonds.
Water clings to polar molecules causing them to be soluble in water (Hydrophilic- attracted to water)
Water tends to exclude nonpolar molecules (Hydrophobic - repelled by water)

Question 2

3 factors that affect boiling point

Answer 2

1) relative strength three intermolecular force
2) molecular mass
3) branching decreases boiling point

Question 3

how does the number of carbon affect the boiling point?

Answer 3

• increase mass
• increase in amount of inter forces
• increase in boiling point

Question 4

Why does branching affect boiling point?

Answer 4

space between molecule = less inter forces

more rod-like the molecules are, the better able they will be to line up and bond

Question 5

what are Aliphatic alcohols?

Answer 5

classified into categories according according to the number of R groups attached to the carbon with the hydroxyl
1 R group: primary alcohol (no branching)
2 R groups: secondary alcohol (same branching)
3 R groups: tertiary alcohol (lots of branching)

Question 6

what are the properties of alcohols?

Answer 6

• capable of hydrogen bonding
• high boiling point
• solubility in water up to 4 carbons, less soluble the more carbons
