Talk:2,4-Dinitrophenylhydrazine

Untitled
Regarding the mechanism of derivative preparation it seems to imply that OH- is the leaving group. A more realistic mechanism would involve the acid-catalysed protonation of OH- to water which is eliminated. In fact, I am certain that this is what happens.

 * I agree. Under acidic conditions you first protonate in general and tend to prefer a positively charged species. In this case first the carbonyl O... but we might want search for a ref supporting this for best quality standards.. regards. Saimondo (talk) 18:40, 1 November 2013 (UTC)

The photograph at the bottom right of the article is captioned "2,4-DNP reacting with 2-heptanone." 2,4-DNP is generally associated with 2,4-Dinitrophenol, not 2,4-Dinitrophenylhydrazine — Preceding unsigned comment added by 121.218.56.254 (talk) 15:36, 4 October 2013 (UTC)
