WebAug 11, 2014 · Salts generally have a very high boiling point (> 1000 °C, much higher than molecular structures) because of the ionic (electrostatic) interaction between the ions, so that one will be at the top. WebHigher melting and boiling points signify stronger noncovalent intermolecular forces. Consider the boiling points of increasingly larger hydrocarbons. More carbons means a …
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.

WebThe melting point of water is about 32 degrees Fahrenheit (0 degrees Celsius) for pure water at sea level (normal elevation). At other elevations the melting point will change due to different pressures from the atmosphere. These changes are discussed further in a section below. Boiling Point of water
