QUESTIONS

◉ Example of Intermolecular Forces Answer: Permanent or
Temporary Dipole


◉ What can intermolecular forces do? Answer: They're responsible
for the solubility of polar and ionic compounds in polar and ionic
solvents. (like dissolves like) and Adsorption


◉ Adsorption Answer: Sticking to a surface


◉ Hydrogen Bonds Answer: The electrostatic interaction between
two polar groups: When a Hydrogen atom is bound to a more
electronegative atom (NOF)


◉ What is the strongest intermolecular force? Answer: Hydrogen
Bonds


◉ Dipole-Dipole Forces Answer: Interactions between molecules
with fixed dipoles (+/- ends): only in polar molecules (water)

, ◉ London Dispersion Forces Answer: Net attractive forces generated
by temporary dipoles: found in all molecules: Weak: contributes to
the attractive forces of molecules in aggregate


◉ Polar Solutes dissolve in... Answer: Polar Solvents


◉ What does Chromatography show? Answer: Differences in
solubility and adsorption


◉ Chromatography Answer: Separates a mixture of chemicals using
a stationary and mobile phase


◉ Stationary Phase Answer: The solid portion that the mobile phase
runs through


◉ Mobile Phase Answer: Contains the dissolved analytes (liquid or
gas), flows over the stationary phase via capillary action


◉ The more soluble an analyte is in the mobile phase... Answer: The
faster it will be transported along the stationary phase


◉ The more strongly the analyte is adsorbed to the stationary
phase... Answer: The slower it will be transported
