The O–H bond energy in water when compared to O–D bond energy in heavy water is

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 : D2O > D2O.
