Answer:
"Water molecules repel nonpolar substances away from itself."
This statement is true because of the following reason :
The attractive force operating between particles of the non -Polar molecules are not overcome by the force between water and non-polar molecule.
Explanation:
For a substance to dissolve in a particular solvent , there should be release of energy.
The force of attraction between the non-polar molecules are weak dispersion forces.
The force of attraction between the polar(water) molecules are dipole - dipole forces .
The non- polar substance will dissolve in the polar substance only when , the force of attraction between Polar(water) and non-polar molecules are greater than their individual force. If this happen , the energy is released and the molecule will dissolve in water.
But ,the energy is not released on addition of non polar molecule to water because the non-polar get squeezed together . This prevent water to interact with them . Hence the non - polar molecules repel water.
Repel nonpolar substances is the part of the statement which is considered as incorrect part about the molecule of water.
Reasons for repulsion of nonpolar substances
Repel nonpolar substances is the statement that is incorrect about the water molecules because nonpolar molecules have no poles on it so the water shows no sigh of repulsion or attraction. Water only dissolve those substances which are not polar in nature.
While on the other hand, water dissolve substances which are polar in nature means making poles so we can conclude that repel nonpolar substances is the part of the statement which is considered as incorrect part about the molecule of water.
