Bond strength and boiling point
WebFeb 23, 2024 · The relationship between bond strength and the melting and boiling points can be explained as the force between the particles increases, and the melting and … WebMar 1, 2024 · This electronegativity difference makes the bond polar, so some compounds are polar. But, polar compounds often dissolve in water. This makes ionic compounds good electrolytes. Due to the strength of the ionic bond, ionic compounds have high melting and boiling points and high enthalpies of fusion and vaporization.
Bond strength and boiling point
Did you know?
WebKey Points. The Lewis theory of covalent bonding says that the bond strength of double bonds is twice that of single bonds, which is not true. General physical properties that can be explained by the covalent bonding model include boiling and melting points, electrical conductivity, bond strength, and bond length. Key Terms WebSep 6, 2024 · As with boiling points, the melting point of a solid is dependent on the strength of intermolecular attractive forces. A strong attraction between molecules results in a higher melting point.
