Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, or between two atoms with sharply different electronegativities, [1] and is the primary interaction occurring in ionic compounds.
Boiling point (°C) K b (°C⋅kg/mol) Freezing point (°C) K f (°C⋅kg/mol) Data source; Aniline: 184.3 3.69 –5.96 –5.87 K b & K f [1] Lauric acid: 298.9 44 –3.9
In such cases, the compounds generally have very high melting and boiling points and a low vapour pressure. [61] Trends in melting points can be even better explained when the structure and ionic size ratio is taken into account. [ 62 ]
The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals ... compounds with ionic bonds have high normal boiling points, ...
Molecular solids have low melting (T m) and boiling (T b) points compared to metal (iron), ionic (sodium chloride), and covalent solids (diamond). [4] [5] [8] [13] Examples of molecular solids with low melting and boiling temperatures include argon, water, naphthalene, nicotine, and caffeine (see table below).
Boiling point: 136.4 °C (277.5 °F; 409.5 K) ... These reactions highlight the influence of electrostatics on the structures of compounds with highly ionic bonding.
The boiling point elevation happens both when the solute is an electrolyte, such as various salts, and a nonelectrolyte. In thermodynamic terms, the origin of the boiling point elevation is entropic and can be explained in terms of the vapor pressure or chemical potential of the solvent. In both cases, the explanation depends on the fact that ...
