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....
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...

1) Water is a polar molecule. There is an effective accumulation of negative charge near the oxygen atom and an effective lack of negative charge ( positive charge) near each of the hydrogen atoms. The molecule is triangular in shape, as diagramed below, with the angle near the oxygen vertex equal to 104.5°. d is the distance from each of the hydrogen atoms to the oxygen atom +Q 5225 52.25 -20 +Q Derive a formula for the electric field produced...

7. If an ionic bond is stronger than a dipole-dipole interaction, how can water dissolve an ionic compound? None of these The ion-dipole interactions of a bunch of water molecules gang up on the strong ionic bond and pull it into the solution. The ions never overcome their interatomic attraction and therefore are not soluble. The ionic bond is weakened by the ion-dipole interactions and ionic repulsion ejects the ions from the crystal. The ion-dipole...

Which of the following statements is NOT true about phenol? Select the correct answer below: The aromatic ring delocalizes and stabilizes the negative charge on the oxygen in the phenoxide ion. Therefore, phenols completely dissociate in water. A phenol will generally form stronger hydrogen bonds than nonaromatic alcohols because the oxygen-hydrogen dipole in the hydroxyl group is stabilized by resonance from the aromatic ring. The phenol functional group is a weak acid in water because the hydroxyl group dissociates slightly....
