2. Identify the strongest type of intermolecular forces in acetone, ethanol, water and hexane. (Structures listed on page 15.) Experiment 2 Intermolecular Forces There are three general types of intermolecular forces. All substances exhibit London Dispersion Forces (LDF), and they are generally the weakest of the three types. These London forces are due to the attractions between small, temporary dipoles that arise from the constant, random movement of the electrons in a substance. As molar mass increases, the size of...

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...

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....
