Abbreviations
The abbreviation "Bn" is frequently used to denote benzyl groups in nomenclature and structural depictions of chemical compounds. For example, benzyl alcohol can be represented as BnOH. This abbreviation is not to be confused with "Bz", which is the abbreviation for the benzoyl group C6H5C(O)−, or the phenyl group C6H5, abbreviated "Ph".

neutral  Germaine: J’en doute énormément. Le texte précise "n=3, 4, 5", donc "B" pourrait être un multiplicateur (en l’occcurrence, billion = milliards d’ions) - mais la balance semble plutôt pencher du côté de la solution offerte par CFournier, en effet.
