Ion and Molecule Interactions

Postby 205389184 » Mon Nov 04, 2019 1:06 am

Will we have to memorize each kJ.mol^-1 value for the interactions that give rise to attractive forces?

We will not have to memorize those values, but know the hierarchy of intermolecular/interionic force strength, which goes from
1. Ion-ion (strongest)
2. Hydrogen bonding
3. Ion-dipole
4. dipole-dipole
5. dipole-induced dipole
6. induced dipole-induced dipole/london dispersion forces/van der waals forces

in general we won have to memorize numbers but I think we might have to know the trend ^^
