  • A bond
  • Polarity

Question 17

Question
Volatility increases as boiling point increases
Answer
  • True
  • False

Question 18

Question
Why do alcohols dissolve in water?
Answer
  • Hydrogen bonds form between the polar -O-H groups of the alcohol and water molecules
  • Hydrogen bonds form between the non-polar -O-H groups of the alcohol and water molecules
  • No bonds form between the alcohol and water molecules which allows the alcohol to dissolve
