Answer #1

London dispersion force is weakest
So, weak IMF
It increases with decrease in r
It is independent of q instead it depends on polarising capability

Dipole - dipole comes next in strength. It is 2nd weakest among all.
So, weak IMF
It increases with decrease in r
It increases with incraese in q


ion dipole comes next in strength.
So, strong IMF
It increases with decrease in r
It increases with increase in q


Hydrogen bonding is strongest
So, strong IMF
It doesn't depend on q and r
