The substance with higher boiling point is to be determined. Concept introduction: The various kinds of interactions that bind a molecule are known as intermolecular forces. These can be forces of dispersion, dipole–dipole, ion–dipole, and hydrogen bonding. Dispersion forces present in every molecule due to the presence of electron. Dipole–dipole 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 boiling point of a compound varies with intermolecular forces and molar mass of a substance. If there are strong intermolecular forces, the boiling point is high and vice-versa. Also, the substance with higher molar mass has higher boiling point.

The substance with higher boiling point is to be determined.
Concept introduction:
The various kinds of interactions that bind a molecule are known as intermolecular forces. These can be forces of dispersion, dipole–dipole, ion–dipole, and hydrogen bonding.
Dispersion forces present in every molecule due to the presence of electron.
Dipole–dipole 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 boiling point of a compound varies with intermolecular forces and molar mass of a substance. If there are strong intermolecular forces, the boiling point is high and vice-versa. Also, the substance with higher molar mass has higher boiling point.
