Answer:
1) dispersion forces
2) ion-dipole forces
Explanation:
For the formation of a solution of the substances, CH3CH2CH2CH2CH3 and CH3CH2CH2CH2CH2CH3, dispersion forces are involved. Recall that the both are organic substances hence they are both molecular in nature. They are not only molecular, they are nonpolar molecules. This implies that only dispersion forces are the possible intermolecular forces.
For the formation of a solution of LiNO3 and H2O, the dipoles of water interacts strongly with the ions Li^+ and NO3^- thereby separating the ions in solution. The positive dipole of water interacts with NO3^- while the negative dipole of water interacts with Li^+.
Therefore, the interaction between nonpolar molecules is dispersion forces while between polar molecules is ion-dipole forces.
- Dispersion forces
- Ion-dipole forces
Dispersion Forces:
They are the weakest form of intermolecular force. The attraction between molecules is temporary.
- it is due to temporary assymetric distribution of electrons in the molecules.
- It is found in the non-polar molecules.
For example- Interaction between [tex]\bold { CH_3CH_2CH_2CH_2CH_3 }[/tex] and [tex]\bold { CH_3CH_2CH_2CH_2CH_2CH_3 }[/tex]
Ion-dipole forces:
The attraction between molecules is due to the interaction between opposite ions of molecules.
- The distribution of electrons is asymmeric.
- This interaction is seen between polar molecules.
For example- Interaction between [tex]\bold { LiNO_3 }[/tex] and [tex]\bold { H_2O }[/tex]
Therefore, the interaction between nonpolar molecules is dispersion forces while between polar molecules is ion- dipole forces.
