Strongest Bonds

Postby LBacker_2E » Thu Nov 14, 2019 9:32 am

In our notes it says bonds between two ions have -250kJ of energy and are most favorable. Is the next most favorable type of bond, a Hydrogen bond?

The next favorable bond would actually be ion-dipole and then after ion-dipole would be hydrogen bonding!

Yes, out of the intermolecular forces for molecules, hydrogen bonding is the strongest.

Covalent bonds are the strongest, followed by ionic bonds. Hydrogen bonds are the strongest type of intermolecular force, followed by London forces and dipole interactions.

A covalent bond is stronger than ionic bond because ionic bonds dissolve in water

Why are hydrogen bonds the strongest?

The order from strongest bonds to least strong bonds are ion-ion, ion-dipole, dipole-dipole (which include H-bonding), induced dipole-dipole, and induced-dipole induced-dipole (van der waals/london dispersion forces).

Intermolecular strengths are: Ion-dipole, H-bond, Dipole-Dipole, Ion-induced dipole, Dipole-induced dipole, and London Forces

The strongest is dipole dipole followed by ion-dipole.

Should we know about how much energy it takes to break each bond?

The next favorable bond would be ion-dipole.

I think the order of the strength of the IMFs according to the textbook (strongest to weakest, by Ep/(kJmol^-1) is: Ion-ion, hydrogen-bonds, ion-dipole, dipole-dipole, dipole induced dipole, induced dipole induced dipole.
