Hello madam,
correction: intramolecular forces are attractive forces that holds atoms together witin a molecule or a substance. The are stronger and are usually called chemical bonds.
intermolecular are weaker attractive forces that exist between molecules.
there are not clear-cut guidlines for which intramolecular forces are strongest because they vary widely interms of stength.
1)ionic bonds= attraction between cations and anions e.g Na-cl
2)covalend bond= between shared pairs of electrons and the nuclie e.g F-H
3)metallic bonds= ATTRACTIVE BETWEEN SEA OF DELOCALISED ELECTRONS e.g Fe-Fe
intermolecular can vary alot too, but there are some more recongnized patterns
1)ion dipole-dipole
2)hydrogen bonds
3)vandawall forces
correction: les verbe au pluriel du passé simple ce conjugue avec l'accent circonflex cette errur ne doir pas etre negliger
