प्रश्न
Explain why:
(1) Interhalogen compounds are more reactive than the related elemental halogens.
(2) Sulphur exhibits the tendency for catenation but oxygen does not.
(3) On being slowly passed through water, PH3 forms bubbles but NH3 dissolves.
उत्तर
(1)
This is because these are polar and have lower bond energies.
(2)
This is because of higher S - S bond energy `((213"kJ")/"mol")` as compared to O-O bond energy `((138"kJ")/"mol")`
(3)
This is because PH3 is insoluble in water (HOH-bonds) but NH3 is highly soluble in water due to H-bonds.
