CHM 142 Exam 1 Questions and Correct Answers Latest Update (2025-2026) Fully Solved
ion dipole - Answers ion interacts with a dipole (polar molecule); attractive force between an ion and a
molecule that has a permanent dipole moment; between ion and polar molecule
dipole dipole - Answers attraction between permanent dipoles; between polar molecules
dipole induced dipole - Answers polar molecule can cause a temporary dipole moment in a nonpolar
molecule; between polar and nonpolar molecules
hydrogen bond - Answers polar molecules containing hydrogen bonds to O, F or N; strongest
intermolecular force (specifically dipole dipole)
dispersion force (london dispersion) - Answers between nonpolar molecules caused by temporary
dipoles in the molecules; present in all atoms
dipole - Answers when atoms become close, electrons of one atom induces a dipole on the other atom
and they attract each other
nonbinding - Answers are intermolecular forces binding or nonbindng?
polar - Answers polar solutes dissolve in _________ solvents
nonpolar - Answers nonpolar solutes dissolve in ___________ solvents
stronger - Answers solute-solute and solvent-solvent interactions are ____________ than solute-solvent
interactions
pressure and temperature - Answers what are 2 important factors of solubility?
hydrophobic - Answers water fearing; repulsive interaction between solute and water
hydrophilic - Answers water loving; attractive interaction between solute and water
higher
lower - Answers the stronger the intermolecular force, the ____________ the boiling point and
__________ the freezing point
longer (larger) - Answers the _______________ the molecule, the stronger dispersion forces will be
which results in a higher boiling point
henrys law - Answers concentration of soluble gas in a liquid is proportional to the partial pressure of
the gas
dipole induced dipole - Answers weak _______________________ interactions between water and
nonpolar molecules allows gas to be soluble in water
, decrease - Answers if there is a decrease in pressure, there will be a ___________ in solubility of gas
decrease - Answers if there is an increase in temperature, there will be a _____________ in solubility of
gas
increase - Answers if there is a _________________ in kinetic energy, there will be a decrease in
solubility of gas
homogeneous - Answers each physical state is called a phase and is a _____________ distinct part of a
system
potential energy - Answers in the form of intermolecular forces, brings molecules together (can be
presented by attraction or repulsion of electrons); stored energy
kinetic energy - Answers connected to the motion of particles and typically separates molecules; related
to the average speed; action
temperature - Answers kinetic energy is dependent on __________________
intramolecular forces - Answers bonding forces that occur inside each molecule

than gas
solid - Answers potential energy is the strongest, almost no kinetic energy
increases - Answers as temperature increases, kinetic energy ________________ causing particles to
move faster and overcome attraction easier
