Ion-dipole forces
This can be seen when sodium chloride (NaCl) dissolves in water. The positive sodium ion (Na+) will be attracted to the slightly negative oxygen atoms in the water molecule, while the negative chloride ion (Cl−) is attracted to the slightly positive hydrogen atoms.
What intermolecular forces are present in NaCl in water?
Ion – dipole forces – Intermolecular force between an ion and the oppositely charged end of a polar molecule. e.g. NaCl in H2O. 3. Dipole – dipole forces – Intermolecular force exhibited by polar molecules in which positive end of one dipole attracts the negative end of another polar molecule.
Do any intermolecular forces occur in NaCl?
What type of intermolecular force in NaCl? The intermolecular forces which contribute the most to the dissolution of NaCl in water is Ion – Dipole Interaction.It is attraction between an ion and a polar molecule.
What causes dissolution of NaCl in water?
When salt is mixed with water, the salt dissolves because the covalent bonds of water are stronger than the ionic bonds in the salt molecules.
When NaCl dissolves in water what is the force of attraction between Na and H2O?
Answer. When NaCl dissolves in water, aqueous Na+ and Cl- ions result. The force of attraction that exists between Na+ and H2O is called an ion-dipole interaction.
Why can salt NaCl be dissolved in water what intermolecular force of attraction IMF is present between salt and water?
Salt (sodium chloride) is made from positive sodium ions bonded to negative chloride ions. Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions.
