How many resonance structures does 2 Nitronaphthalene have?
Attack at C-2 Nitration at C-2 produces a carbocation that has 6 resonance contributors.
What are the products of nitration of naphthalene?
Nitration at position 1 produces a carbocation that has 7 total resonance structures, 4 of which appear to preserve the aromaticity of the second ring. Nitration at position 2 produces a carbocation that has 6 total resonance structures, 2 of which appear to preserve the aromaticity of the second ring.
Does naphthalene show nitration?
Abstract. Naphthalene was nitrated with a variety of nitrating agents. 99, 5516-5518] shows that nitration of naphthalene gives an α-nitronaphthalene to β-nitronaphthalene ratio that varies between 9 and 29 and is thus not constant.

Which of the following is the most stable structure?
( C) Structure (c) is the most stable resonance structure.
What is Sulphonation of naphthalene?
Aromatic sulfonation is a very important chemical transformation of organic compounds. 1,2 In the sulfonation of naphthalene, two isomers of α or β-sulfonic acid are formed, while the isolation of the indivisual compound is usually very difficult.
How will you prepare alpha Nitronaphthalene from naphthalene?
1-Nitronaphthalene can be synthesized from naphthalene using a classical nitration mixture (HNO3+H2SO4) in a yield of 95% (Fierz-David and Blangey, 1949; Duvalma et al., 1964). In addition, 90% HNO3 can be used to carry out the reaction in acetonitrile with 85% yield (Wright, 1965).
Which resonance is most stable?
Rules for Estimating Stability of Resonance Structures
- The resonance structures in which all atoms have complete valence shells is more stable.
- The structures with the least number of formal charges is more stable.
- The structures with a negative charge on the more electronegative atom will be more stable.
Which of the following is most stable resonance?
How is nitronaphthalene used as an environmental contaminant?
1-nitronaphthalene is a mononitronaphthalene substituted by a nitro group at position 1. It has a role as an environmental contaminant and a mouse metabolite. Nitronaphthalene appears as a yellow crystalline solid. Insoluble in water and denser than water. May irritate skin and eyes.
What are the long term effects of 2-nitronaphthalene?
Toxic to aquatic organisms, may cause long-term adverse effects in the environment. 2-nitronaphthalene is a mononitronaphthalene carrying a nitro group at position 2. Computed by InChI 1.0.5 (PubChem release 2019.06.18)
Which is a Mononitronaphthalene substituted by a nitro group?
1-nitronaphthalene is a mononitronaphthalene substituted by a nitro group at position 1. It has a role as an environmental contaminant and a mouse metabolite. Nitronaphthalene appears as a yellow crystalline solid.
What kind of solid is nitronaphthalene in water?
Nitronaphthalene appears as a yellow crystalline solid. Insoluble in water and denser than water. May irritate skin and eyes. Readily ignitable and may be difficult to extinguish once ignited. Used to make dyes and other chemicals.
