Which is more basic O nitroaniline or p-nitroaniline?
p-nitroaniline is more basic than o-nitroaniline. The nitro group is an electron withdrawing group. When attached on the benzene ring, it activates the ring by pulling the electrons towards itself. On the other hand, in para isomer the distance between the NH2 group and NO2 group increases.
What are the resonance structures of oxygen?
A molecule or ion with such delocalized electrons is represented by several contributing structures (also called resonance structures or canonical forms). Such is the case for ozone (O3), an allotrope of oxygen with a V-shaped structure and an O–O–O angle of 117.5°.
What is the structure of p-nitroaniline?
Is o2 a resonance structure?
The two oxygens are both partially negative, this is what the resonance structures tell you! This is important because neither resonance structure actually exists, instead there is a hybrid. The oxygens share the negative charge with each other, stabilizing it, and reducing the charge on either atom.
Which is the correct formula for 4-nitroaniline?
4-Nitroaniline. 4-Nitroaniline, p-nitroaniline or 1-amino-4-nitrobenzene is an organic compound with the formula C 6 H 6 N 2 O 2. It is an organic chemical compound, consisting of a benzene ring in which an amino group is para to a nitro group. This chemical is commonly used as an intermediate in the synthesis of dyes, antioxidants,…
How many resonance structures can be drawn for ozone,?
Ozone, or O3, has two major resonance structures that contribute equally to the overall hybrid structure of the molecule. The total number of valence electrons the ozone molecule has is equal to 18 – 6 electrons from each oxygen atom. The two possible Lewis structures that can be drawn for ozone are.
What are the effects of exposure to p-nitroaniline?
Inhalation or ingestion causes headache, drowsiness, shortness of breath, nausea, methemoglobinemia, and unconsciousness; fingernails, lips, and ears become bluish; prolonged and excessive exposures may also cause liver damage. Contact with eyes causes irritation and possible corneal damage.
Which is the most stable structure of Nitro 4?
Here, resonance forms 2 and 4 have the negative charge on carbon, whereas structure 3 has it on oxygen. 3 is therefore the most stable resonance structure. Incidentally, all of the resonance forms 2 through 4 have complete conjugation throughout the molecule so that’s not a factor.
