D2o is preferred to h2o

WebD2O exhibits about 2600 times neutron-moderating ability compared to H2O. This has contributed to the revolution in nuclear power production as D2O provided an optimized source as a moderator in pressurized heavy water reactor (PHWR). WebDec 8, 2014 · I think in water and D2O the main factor is not Van Der Waals but rather hydrogen bonding. So the boiling point of D2O is higher than H2O not because of the London forces, but because of the difference in electronegativity between the hydrogen and the water, creating an electrostatic attraction.
