Water is a polar molecule, meaning it carries partial charges (δ
or δ❝) on opposite sides of the molecule. For two formula units of
NaCl, drag the sodium ions and chloride ions to where they would
most likely appear based on the grouping of the water molecules in
the area provided. Note that red spheres represent O atoms and
white spheres represent H atoms.

Predict which intermolecular forces contribute the most to the dissolution of NaCl in water?
NaCl is an ionic solid. The Na+ and Cl− ions in NaCl are bonded through an electrostatic force of attraction commonly known as the ionic bond. Water is a polar solvent. The oxygen atom, being more electronegative, attracts the electron cloud toward itself. As the electron cloud is pulled by the oxygen atom, it carries a partial negative charge, and the hydrogen atoms carry a partial positive charge. This partial separation of charges in the water molecule makes it polar....

Try this example with water first: H1 H1 H2 H2 H H Water, H20 Partial charges: His +0.38, O is -0.75 Formal charges: His O, O is o Oxidation State: His +1, O is-2 Electrostatic potential description: The blue (positive) and red (negative) potentials are separated. That makes the molecule polar. The molecule is dark blue (quite positive) over the hydrogen atoms and dark red (quite negative) over the oxygen atom, making water very polar. And now do these two...

A covalent bond is a bond in which electrons are shared between atoms of elements
A covalent bond is a
bond in which electrons are shared between atoms of elements. A
covalent bond can be polar or nonpolar. In a nonpolar covalent
bond, the bond is between two identical atoms and the electrons are
evenly shared between the atoms.In contrast, in a
polar covalent bond, the bond is between two nonidentical atoms and
the electrons are unevenly shared between the atoms. The uneven
sharing of electrons takes place because of the difference in the
electronegativity...
