Question

In which of the following compounds the Hydrogen can be exchanged by deuterium when they added to D2O​

Answer 1

Answer:

Due to the acidic nature of α hydrogens they can be exchanged with deuterium by reaction with D2O (heavy water). The process is accelerated by the addition of an acid or base; an excess of D2O is required. The end result is the complete exchange of all α hydrogens with deuterium.
