Hydrogen–deuterium exchange (also called H–D or H/D exchange) is a chemical reaction in which a covalently bonded hydrogen atom is replaced by a deuterium atom, or vice versa. It can be applied most easily to exchangeable protons and deuterons, where such a transformation occurs in the presence of … See more In protic solution exchangeable protons such as those in hydroxyl or amine group exchange protons with the solvent. If D2O is solvent, deuterons will be incorporated at these positions. The exchange reaction can be followed … See more H–D exchange was measured originally by the father of hydrogen exchange Kaj Ulrik Linderstrøm-Lang using density gradient tubes. In modern times, H–D exchange has primarily been … See more • David Weis, Ed. (2016). Hydrogen Exchange Mass Spectrometry of Proteins: Fundamentals, Methods, and Applications. New York: Wiley.

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. What does d2 mean in organic chemistry? Hydrogen-d2.

WebJan 29, 2024 · Example 22.3. 1. A simple method for determining the number of α -hydrogen in a compound is through reaction of D 3 O +. The reaction product is then isolated and its molecular weight is determined by mass spectrometry. For example, if cyclopentanone is reacted with D 3 O +, the isolated product has a molecular weight of 88 g/mol.
