WebNov 17, 2014 · The main point is that the natural abundance of D is only ~110 parts per million, so you need very large scale industrial processes to separate the D from H. Also, since the abundance of D is so low, there is almost no D 2 O in nature - it will almost all be D H O. – Jon Custer Nov 17, 2014 at 18:05 2 Agree with Custer. 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.
