The value of ........ is less for D2O compared to that of H2O.

All physical constants OF: D2O > H2OReason: Physical properties  α Molecular massException: Dielectric costant: H2O > D2ODielectric constant is a measure of ionisation of a Salt  by the solvent example: →Density:D2O>H2O→Boiling point D2O > H2O→ Latent heat of vapoursation : D2O > H2O→ Dielectric constant : H2O>D2O
