FREE Expert Solution

We are being asked to rank the given compounds in order of decreasing surface tension at a given temperature.


Surface Tension

▪ is the energy required to increase the surface area of a liquid by a unit amount.
influenced by intermolecular forces between molecules


Intermolecular Forces (IMF) are the attractive forces between 2 molecules.

Ion-dipole

strongest IMF
▪ deals with the attraction between an ion and a polar compound.
