Question
Answer the following questions about acetone and 2-propanol based on your knowledge of their intermolecular interactions. What types of intermolecular interactions would be present between acetone molecules in a solution of only acetone molecules? What types of intermolecular interactions would be present between 2-propanol molecules in a solution of only 2-propanol molecules? Which of the two molecules has the stronger intermolecular interactions? Which of the two molecules has the higher boiling point? of the two molecules will have the higher vapor pressure?Explanation / Answer
(CH3)2CO Intermolecular Forces:
The intermolecular forces acting on two atoms of Acetone would be London Dispersion Forces and Dipole-Dipole Forces. This is because the atom has only side that is more positively charged than the other causing the Dipole-Dipole attraction.
1. London Dispersion Forces- This is the most common type of intermolecular force. It is the attraction of two dipoles created temporarily in adjacent molecules
2. Dipole-Dipole Forces- These are active when the negative pole of one polar molecule is attracted it the positive pole of another polar molecule.
