Title: What is the difference between dipole-dipole force and ion-dipole force?
Post by: jessiele on June 03, 2012, 03:37:35 pm

I'm a bit confused about the intermolecular forces of dipole-dipole and ion-dipole force?
CH3Cl : ion-dipole, why is it?( from STAV trial exam 2012)
pleasee help

Isn't it dipole-dipole forces for chloromethane?

so does it mean CH3Cl is a polar molecule like CH3OH?
because what I know from searching is dipole-dipole force only present in polar molecules

it would be ion dipole if it reacted with water
but dipole - dipole between chloro ethane molecules
