need explanations on Chemistry cie

(1/1)

The SMA:
hey guys, what does enthalphy changes of vaporisation means?
n why does its related to indicate the relative strength of
hydrogen bonds between the molecules in liquid Hydrogen halide?

cashem'up:
the enthalpy of vaporisation is the energy change required in order to form 1 mole of vaporised products............. now as we know when something vaporises INTERMOLECULAR FORCES ARE BROKEN...... now in  hydrogen halides there is presence of dipole-dipole forces between molecules which are broken during vaporisation and thus if the enthalpy change is more positive then the bonds must have been more stronger......

hope it helps thx :P

The SMA:
thaaaaanks ima shah
really really appreciate it! :)

cashem'up:
no probs
 ;D ;D ;D
