At given temperature the given hydrocarbons are to be predicted in order of increasing vapour pressure and have to be explained. Concept introduction: Vapour pressure: In a closed system, vapour pressure is the pressure produced by a vapour in thermodynamic equilibrium with its solid or liquid phase at a given temperature. Intermolecular forces are Van der Waals forces. They are weak and have two types viz., London dispersion forces, dipole-dipole forces and hydrogen bonding. Hydrogen bonding is relatively the strongest one. Intermolecular forces are the forces acting between molecules whereas Intramolecular forces are the forces that operate within a molecule. Hydrogen bonding is a special type of Dipole-dipole forces but stronger than the former. London dispersion forces exist in non-polar covalent compounds whereas dipole-dipole forces exist in polar covalent compounds but both are weak. Larger the molecular size, stronger the London dispersion force. Arrangement of major types of intermolecular forces in increasing order of strength: London dispersion forces < Dipole-dipole forces < Hydrogen bonding

Interpretation Introduction
Interpretation:
At given temperature the given hydrocarbons are to be predicted in order of increasing vapour pressure and have to be explained.
Concept introduction:
Vapour pressure: In a closed system, vapour pressure is the pressure produced by a vapour in thermodynamic equilibrium with its solid or liquid phase at a given temperature.
Intermolecular forces are Van der Waals forces. They are weak and have two types viz., London dispersion forces, dipole-dipole forces and hydrogen bonding. Hydrogen bonding is relatively the strongest one.
Intermolecular forces are the forces acting between molecules whereas Intramolecular forces are the forces that operate within a molecule.
Hydrogen bonding is a special type of Dipole-dipole forces but stronger than the former.
London dispersion forces exist in non-polar covalent compounds whereas dipole-dipole forces exist in polar covalent compounds but both are weak.
Larger the molecular size, stronger the London dispersion force.
Arrangement of major types of intermolecular forces in increasing order of strength:
