Question 25 3.5 pts A 0.258-g sample of a pure triprotic acid, H3A, (where A is the generic anion of the acid), was dissolved in water and titrated with 0.150 M barium hydroxide solution. The titration required 13.9 mL of the base to reach the equivalence point. What is the molar mass of the acid ? 227 g/mol 82.5 g/mol 371 g/mol 124 g/mol 186 g/mol Question 24 1.5 pts Which of the following compounds would have...

INTERMOLECULAR FORCES INTRODUCTION LEARNING OBJECTIVES To relate the effecet of intermolecular forces on relative melting points and vapour pressures of some organic substances THEORY Weak attractive forces that occur between individual molecules in substances are called intermolecular forces. These include London dispersion forces, dipole-dipole forces and hydrogen-bonding forces. Collectively, the three types of intermolecular forces are referred to as Van der Waals forces. These attractive forces are much weaker than the chemical bonds between atoms in a molecule. Note that...
My answers: Not sure if they are correct.
1. a. London dispersion
b. H-bonding, dipole-dipole, london dispersion
c. London dispersion
d. Ionic, london disperson
2. The second one because not a lot of H+ and less acidic. Need
help understanding the meaning of the question.
3. Diethyl cannot h-bond because it does not provide intermolecular
bonding engery while 1-b. can form h-bond making strong
intermolecular bonds to take up greater engery to break
molecules.
4. Not sure...
