The false statement out of the given statements is to be determined. Concept introduction: Intermolecular forces refer to the interactions between the molecules. They are of four types, namely, dispersion forces, dipole–dipole interactions, hydrogen bonding, and ion-dipole forces. Dispersion forces present in every molecule due to the presence of electron. Dipole–dipole interaction is the attractive force between opposite end of polar molecule. Hydrogen bonding is the attractive force between hydrogen attached to an electronegative atom of one molecule and an electronegative atom of different molecule. Ion-dipole force is the attractive force that due to electrostatic attraction between an ion and a neutral molecule.

The false statement out of the given statements is to be determined.
Concept introduction:
Intermolecular forces refer to the interactions between the molecules. They are of four types, namely, dispersion forces, dipole–dipole interactions, hydrogen bonding, and ion-dipole forces.
Dispersion forces present in every molecule due to the presence of electron.
Dipole–dipole interaction is the attractive force between opposite end of polar molecule.
Hydrogen bonding is the attractive force between hydrogen attached to an electronegative atom of one molecule and an electronegative atom of different molecule.
Ion-dipole force is the attractive force that due to electrostatic attraction between an ion and a neutral molecule.
In the Thermo Fisher application note about wine analysis (Lesson 3), the following
chromatogram was collected of nine components of wine. If peak 3 has a retention time of
3.15 minutes and a peak width of 0.070 minutes, and peak 4 has a retention time of 3.24
minutes and a peak width of 0.075 minutes, what is the resolution factor between the two
peaks? [Hint: it will help to review Lesson 2 for this question.]
