Correct order of bolinge point among H2O,H2O2,D2O in decending
order

Ram Saroj Dubey · Accepted Answer

Dear Student, D2O have a higher boiling point then H2O because of
the hydrogen bonding Hydrogen bonds in deuterium oxide are slightly
stronger than H2O H2O2 also have higher boiling point than H2O
because hydrogen peroxide has more electrons, which gives a greater
polariability for H2O2 and stronger London dispersion forces H2O2
has a much greater dipole moment than does water And boiling point
of H2O2 is more than D2O because H2O2 has more electrons, which
gives a greater polariability for H2O2 and stronger London
dispersion forces Hence boiling point order will be
H2O2>D2O>H2O Regards
