To choose the molecule having the higher boiling point and to give a brief account for the intermolecular forces that influenced the boiling point of the corresponding molecule. 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. As the molecular mass increases the energy required to get over the intermolecular forces increases

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.
As the molecular mass increases the energy required to get over the intermolecular forces increases

Photochemical smog is formed in part by the action of light on nitrogen dioxide. The wavelength of radiation absorbed by NO2 in this reaction is 197 nm.(a) Draw the Lewis structure of NO2 and sketch its π molecular orbitals.(b) When 1.56 mJ of energy is absorbed by 3.0 L of air at 20 °C and 0.91 atm, all the NO2 molecules in this sample dissociate by the reaction shown. Assume that each absorbed photon leads to the dissociation (into NO and O) of one NO2 molecule. What is the proportion, in parts per million, of NO2 molecules in this sample? Assume that the sample behaves ideally.
