WebTo answer the first question, a molecule must have a charge to dissolve in water, because for a substance to dissolve, it has to form bonds with the solvent, and it cant do that unless it is polar 2. It happens with polar molecules (like methanol), as … WebThe simpler carbohydrates resemble water molecules in one important respect. Their primary hydrogen-bonding function comes from the hydroxyl group which can have both donor and acceptor properties (Box 13.1). For this reason, their hydrogen-bonding patterns have features in common with those of the ices and the high hydrates.

WebA hydrogen bond is a weaker form of the bond than the covalent bond formed by the hydrogen atom and another element. A hydrogen bond is comparatively stronger than a simple dipole-to-dipole bond but weaker than an ionic bond. Hydrogen bonding occurs due to the attraction of two or more electrically charged molecules, which have a small … WebHydrogen bonds form when hydrogen atoms covalently bonded to nitrogen (N), oxygen (O), or fluorine (F) in the form of covalent compounds such as ammonia (NH 3), water (H 2 O) and hydrogen fluoride gas (HF). In these molecules, the hydrogen atoms do not pull as strongly on the shared electrons as the N, O, or F atoms. Therefore, the molecules ...
