Bond Strength

Postby Jarrett Peyrefitte 2K » Sun Nov 10, 2019 11:58 pm

Which bonds are stronger, covalent or ionic? What is the conceptual reasoning behind it?

Ionic bonds are typically stronger than covalent because of the coulombic attraction between ions of different charge

Ionic bonds are stronger because there is a greater electronegativity difference between the two atoms (greater than 2.0). Also, while covalent bonds share electrons, ionic bonds are formed by the mutual attraction from both of the oppositely charged ions.

Another important thing to note from the midterm is bond strength and length between single, double, and triple bonds. These are the trends:
Bond Length: single bond > double bond > triple bond
Bond Strength: triple bond > double bond > single bond

Ionic bonds (although some share covalent bond features) are generally stronger since they are completely transferring electron(s) to the other. Conceptual reasoning is the fact that their electronegativity differences are more drastic.

Ionic bonds are stronger than covalent bonds because in covalent bonds, the electrons are shared so it has a lower electronegativity. Highly charged ions will have stronger bonds than ions with small charges.

A general pattern for bond strength from strongest to weakest is ion-ion interactions (ionic bonds), ion-dipole interactions, dipole-dipole interactions, dipole-induced dipole interactions, induced dipole-induced dipole interactions.

Ionic bonds are stronger because there is a greater charge difference between atoms and thus a higher attraction.

Ionic is stronger than covalent bonds since they have a greater attraction towards each other due to the opposite charges that ionic bonds possess that covalent bonds don't
