Answer to Question #298879 in General Chemistry for aaaa

Question

At 50°C, the vapor pressure of ethanol is 0.30 atm, acetic acid

is 0.08 atm, water is 0.12 atm, and acetone is 0.84 atm. Arrange these substances in

order of increasing manner:

1. rates of evaporation.

2. boiling point temperature.

3. vapor pressure.

4. viscosity.

5. intermolecular forces.

Answer 1

a. In order of increasing rates of evaporation: acetic acid<water<ethanol<acetone (higher values of vapor pressure correspond to higher rates of evaporation);

b. In order of increasing boiling points: acetone<ethanol<water<acetic acid (higher values of vapor pressure correspond to lower values of boiling point);

c. In order of increasing IMF: acetone<ethanol<
