What is the melting point of nitronium in naphthalene?
The purpose of this experiment was to nitrate naphthalene with nitronium ion, which is formed at low concentration from a reaction of nitric acid and sulfuric acid. The percent yield from the experiment was 54.4% of the product, and the melting point of the possible results were 59 °C for 1-nitronaphthalene, and 78°C for 2-nitronaphthalene.
Which is the electrophile in naphthalene mononitration?
The electrophile is the nitronium ion, NO2+, which is formed at low concentration by a reaction of the two acids. The mononitration of naphthalene could lead to either one of two products, 1-nitronaphthalene or 2-nitronaphthalene.
