Question

Which are the strongest intermolecular forces or intramolecular forces? Which are the strongest intermolecular forces? Where are they found (see question #18)? Why does water not follow the trend in properties as seen for the other compounds of hydrogen and Group 6A elements (H_2Te, H_2Se. H_2S) especially in regards to boiling point? What are two factors that affect the strength of dipole-dipole attractions? What are two factors that affect the strength of London dispersion forces (Van der Waals)?

Explanation / Answer

17 ) intermolecular are stronger because they are inbetween two or more different units

18) hydrogen bond is the strongest intermolecular force because it is inbetween high electronegative atom and hydrogen it looks like ionic bond almost

19) we can found in HF , NH3 , H2O , phenol , alcohol etc molecules

20) H2O can form hydrogen bond but not others . due to this reason H2O can behave abnormally in 6th group hydrides

21)

a) size of ion

b) polarity of molecule

22)

a) molar mass of atom or molecule

b) space (area) occupied by the molecule
