Question

Fluro-2,4-dinitrobenzene is highly reactive toward nucleophillic substitution through an SNAr mechanism. What product would be formed when 1-fluro-2,4-dinitrobenzene reacts with each of the following reagents ?

Answer 1

Answer:

1-Fluoro-2,4-dinitrobenzene (commonly called Sanger's reagent, dinitrofluorobenzene, DNFB or FDNB) is a chemical that reacts with the N-terminal amino acid of polypeptides. This can be helpful for sequencing proteins.
