Why are most organic compounds nonconducting and insoluble in water? Check all that apply. They don't conduct electricity because they are covalent, not ionic. Most organic compounds don't dissolve in water because they are polar. Most organic compounds don't dissolve in water because they are nonpolar. They don't conduct electricity because they are ionic, not covalent.

What is the importance of the 2′ hydroxyl group in the ribose sugar of an RNA molecule? Check all that apply. View Available Hint(s) Hint 1. Properties of an hydroxyl groupopened hint A hydroxyl group has the formula OH. Water, alcohols, carboxylic acids, and other hydroxy-containing compounds can be deprotonated owing to the high electronegativity of oxygen, resulting in a stable conjugate base. Hydroxy-containing compounds are also able to form hydrogen bonds, which lead to higher boiling and melting points...

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...
