Deuterated molecules (in which hydrogens have been partially or fully replaced by deuterium) have similar properties to their hydrogen monologues. For example, [[Heavy water|deuterated water]] has a boiling point of 101.4 degrees [[Celsius]] compared to [[water|normal water]], with a boiling point of 100 Celsius. | Deuterated molecules (in which hydrogens have been partially or fully replaced by deuterium) have similar properties to their hydrogen monologues.
