Question

I need help with 2, 3 and 5. thank you.

2. Identify all the types of intermolecular forces found in cach of the following compounds. n-pentane CH3(CH2)3CH 2-butanone CH CCH CH 1-butanol CH3(CH2)2CH2OH Write a chemical equation that describes the phase change from liquid pentane to gaseous pentane the change in enthalpy of this reaction called? 3. 4. What are the safety hazards associated with the chemicals used in this experiment? 5. What is the difference between the pressure exerted by a vapor and the vapor pressure of a substance

Explanation / Answer

2. Intermolecular forces

n-pentane : London dispersion forces

2-butanone : dipole-dipole force and London dispersion force

1-butanol : Hydrogen bonding, dipole-dipole force and London dispersion force

3. Chemical equation,

pentane (l) --> pentane (g)

This is enthalpy of vaporization

5. Pressure exerted by vapor is unidirectional towards the liquid state of substance, it may be lower or higher than the pressure exerted by surface of non-vapor state of substance, whereas, vapor pressure is the pressure exerted by the vapor state of the substance in equilibrium with the liquid state of substance.
