Hint: The boiling point is one of the physical properties of the compound. The boiling point is important for phase transfer properties. The boiling point means liquid to gas transferring point. The temperature at first gaseous molecules exit from the liquid form of the compound. The boiling point of molecules is very important for the distillation process. Without hydrogen bonds nothing in the world. There are two types of hydrogen bonds. There are intermolecular hydrogen bonds and intramolecular hydrogen bonds. The hydrogen bond is dependent on the most electronegativity atom in the molecule.
Complete answer:
We have to know that the dipole- induced dipole interaction is one of the forces in science and it became the strong intermolecular force in the molecules.
The molecular formula of methanol is \[{\text{C}}{{\text{H}}_{\text{3}}}{\text{OH}}\]. The molecular formula of carbon tetrachloride is\[{\text{CC}}{{\text{l}}_4}\].
The boiling point of methanol is \[64.7^\circ C\]. The boiling point of carbon tetrachloride is \[76.7^\circ C\].
Carbon tetrachloride has lower vapour pressure than methanol, hence the boiling of methanol is lower than carbon tetrachloride.
When we add methanol to carbon tetrachloride, dipole-dipole interaction will increase in the solution.
The boiling point of the molecule depends on the molecular mass, type of bonding in the molecule and functional group in the molecule.
If we want to order the boiling point of the molecules, first know the molecular mass of the given molecules, the type of bonding in the molecules and also depend on Van Der Waals force and dipole-dipole interaction.
Note:
We need to know that the molecule which has the highest mass compared to the other molecules, will have a high boiling point compared to others. If two molecules having same molecular mass means, then next focus on the hydrogen bonding and Van Der Waals force. If two molecules having same molecular mass, one molecule is having hydrogen bond and other one not having hydrogen bond means, molecule which present hydrogen bond that is stronger than other one. Hence, the molecule has a hydrogen bond that is high boiling point. If two molecules have the same mass but both are not having hydrogen bonds, the next focus on the Vander Waals force in the molecules. The molecule which has the lowest Van Der Waals force has a lower boiling point than others. The Dipole-Dipole interaction is also important for boiling point.
