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....

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....

please solve all.
Hydrogen bonds are noncovalent interactions between a hydrogen atom with a partial positive charge, called the hydrogen bond donor, and an atom with a partial negative charge, called the hydrogen bond acceptor. Progesterone is a hormone that contains two ketone groups. The oxygen in the ketone group can function as a hydrogen bond acceptor. н, со CH, Select the amino acids that have side chains that can form a hydrogen bond with progesterone at pH 7. tryptophan...

What is responsible for the differences in chemical shift observed in carbon 4 in 4-fluoroheptane and carbon 4 in heptane? 2 Check all that apply View Available Hint(s) The electronegative fluorine atom generates a partial positive charge on carbon 4, which results in a downfield shift of the carbon signal. There is no difference in the chemical environment between the carbon 4 in heptane and 4-fluoroheptane, so there is no difference in chemical shift. The hybridization of carbon 4 has...

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...
