Can someone please explain to me the sub-topic on intermolecular forces, including formation of instantaneous and permanent dipoles, hydrogen bonding and how intermolecular forces and dipoles make a compound soluble or not, solid or liquid at r.t.p or not et cetra. :|

Hydrogen bonding exists if an atom is surounded by FON (Flourine, oxygen or nitrogen) on both sides. Eg hydrogn bnding in h20 exists since H is suroundd by oxygen on 1 water molecule and another oxygen frm 2nd water molecule.draw ths n u'll it.It is the strongest intermolecular force. Permanet dipoles exist in ions (ionic dipole) and atöms hvng electronegativity diff. And van der waal frces exist b/w non polar molecules. Thy r the weakest of all.nw solubility depends on intermolecular frcez. A non polar solvent wont dissolve in water cos the energy releasd when van dr waal frces break is nt enough to break hydrogn bndin in water molecules.so they cnt H-bond wth water. While a nonpolar solvent disolves non polar cmpound cos energy releasd whn van dr wal frces break in non polar cmpd is enough to break van dr wal frcs in solvent and bond to solvent n thereby disolvng in it. So remembr 1 thng... A strong force in a cmpound can break a weak force in solvent and cn dissolve in it. Hope tht helps.
