what is meant by intermolecular collution
Answers
forces are attractive forces between the molecule that only requires less bond enthalpy to break the bonds of the molecules because it weaker than intramolecular forces which is the attractive forces within the molecules. It has three types: dispersion forces, hydrogen bonding and dipole-dipole bonding. London dispersion forces is spontaneous in all kinds of compounds either ionic or covalent (polar or nonpolar), dipole-dipole and hydrogen bonding are present in benzoic and urea as to why the actual melting point of these compounds are very high while in naphthalene, it is a nonpolar compound and the only IMF that is present is dispersion force given that there are no electronegative elements such as N, O and F associated with this compound. Benzoin holds the largest molar mass but its melting point is lower than urea, benzoin, and salicyclic acid that’s because the nuclei do not tightly hold its electrons because it is polar, increasing melting point as increasing molar mass is only applicable if and only, the compounds are nonpolar covalent[Cha10]. Sublimation is the transition of solid to gas
