Students have asked these similar questions
explain why the hydrogen bond intermolecular forces are stronger than ordinary dipole-dipole intermolecular forces. You may use Coulomb’s Law to help justify your answer.
Why does the temperature of a substance not change when the phase changes?
1.) The energy is going into breaking/forming intermolecular interactions, allowing for phase change
2.) The energy must be converted to another form of radiation before it can increase the temperature
3.) The temperature changes but not enough to be measured
4.) The matter absorbs all the energy into the covalent bonds of the molecule, preventing any temperature change.
Two students plan and carry out an investigation to determine if ionic or covalent
bonds have stronger intermolecular forces; they use salt and sugar. They collect the
following data:
Sugar (covalent)
white
Salt (ionic)
white
rough, very small
grains
rough, small grains
soluble

Which of the following tests will most help them to infer the strength of
intermolecular forces between ionic and covalent compounds?
