Among liquid bromine and the interhalogen compound, the compound having higher boiling point should be identified. Also the reason for the difference in boiling point should be stated. Concept introduction: The set of repulsive and attractive force between molecules that result from the polarity between neighboring molecules is represented as intermolecular force. There are four types of intermolecular forces: Hydrogen bonding London dispersion force Ion – dipole force Dipole – Dipole force Ion – dipole force is a strong intermolecular force as it contains both ionic and polar bonds. Hydrogen bond: Hydrogen is bonded to strong electronegative atom like oxygen, nitrogen etc. Dipole – Dipole: This force takes place between two polar compounds. London dispersion force: This force is present in all compounds and is a weak force.

Concept introduction: The set of repulsive and attractive force between molecules that result from the polarity between neighboring molecules is represented as intermolecular force. There are four types of intermolecular forces:
Hydrogen bonding
London dispersion force
Ion – dipole force
Dipole – Dipole force
Ion – dipole force is a strong intermolecular force as it contains both ionic and polar bonds.
Hydrogen bond: Hydrogen is bonded to strong electronegative atom like oxygen, nitrogen etc.
Dipole – Dipole: This force takes place between two polar compounds.
London dispersion force: This force is present in all compounds and is a weak force.
The representation of a one-dimensional velocity distribution function for a gas, as the temperature increases:a) it becomes more flattenedb) the maximum occurs for vi = 0 m/sExplain it.
The velocity distribution function of gas moleculesa) is used to measure their velocity, since the small size of gas molecules means that it cannot be measured in any other wayb) is only used to describe the velocity of particles if their density is very high.c) describes the probability that a gas particle has a velocity in a given interval of velocities
Explain why in the representation of a one-dimensional velocity distribution function for a particular gas, the maximum occurs for vi = 0 m/s.
