a) Identify the Intermolecular forces from STRONGEST to WEAKEST (strongest on the top) and place the following compounds in the appropriate row by identifying which Intermolecular forces they have. :
N2, HI, HF, CH3-CHO, CH3OH, NH3, H2O, NaCl
(b) Then rank the compounds from lowest boiling point to highest. N2, HI, HF, CH3-CHO, CH3OH, NH3, H2O, NaCl
