The bond in HF, however, is more polar than would be expected for the union of two adjacent members of the same family, and hydrogen is therefore not a typical member of family VIIA. WebCorrect option is B) Option B is the correct answer. Both H 2O and HF have electronegative oxygen and fluorine atoms respectively in their molecule. In fact, Fluorine is more electronegative than Oxygen, so technically, HF should engage in more hydrogen bonding than water. But the scenario is different. Each water molecule has two hydrogen atoms. telekom craiova deranjamente

WebHydrogen fluoride, HF, has one bond, but four centers of electron density around the fluorine. Since it has only two atoms - they must by definition lie on a line - and therefore we do not need to discuss the “shape” of HF. WebHydrogen bonds are a type of dipole-dipole interactions that occur between hydrogen and either nitrogen, fluorine, or oxygen. Hydrogen bonds are incredibly important in biology, because hydrogen bonds keep the DNA bases paired together, helping DNA maintain its unique structure. Dipole Forces
