Why is o-nitroaniline less polar than p-nitroaniline?
The proximity of amino and nitro functional groups in o-nitroaniline results in intramolecular hydrogen bonding, making the molecule less polar. In p-nitroaniline, the amino group is para or opposite to the nitro group making the molecule more polar.
How will synthesis p-nitroaniline from acetanilide?
The organic compound p-nitroacetanilide is prepared from acetanilide through nitration. When acetanilide is treated with nitrating mixture that is a mixture of nitric acid and sulphuric acid p-nitroacetanilide is formed. Along with p-nitroacetanilide, o-nitroacetanilide is also formed as a minor product.
Is p-nitroaniline an acid or a base?
Secondly, aniline and p-nitroaniline (first two green shaded structures) are weaker bases due to delocalization of the nitrogen non-bonding electron pair into the aromatic ring (and the nitro substituent). This is the same delocalization that results in activation of a benzene ring toward electrophilic substitution.
Is p-nitroaniline soluble in water?
Insoluble in water. This chemical is sensitive to moisture. Special Hazards of Combustion Products: Toxic oxides of nitrogen may form in fire.
Why is p-nitroaniline Coloured?
Trouble is that traces of acid left will hydrolyze it into p-nitroaniline which has deep yellow to yellow-orange color (this compound has melting point of 146 -149 °C) and it smells like ammonia. Unfortunately, p-nitroaniline is difficult to remove from p-nitroacetanilide by crystallization.

Why does fluorene move faster down the column than Fluorenone?
Why? Fluorene moves faster because its’ polarity is the same as hexane and also opposite of the alumina gel.
What is P Nitroacetanilide used for?
Mention the uses of p-nitroacetanilide. It is used in pharmaceuticals in preparation of paracetamol and phenacetin. Used in pesticides and rubber chemicals also used as an intermediate for dyes.
What are the three steps used to synthesize p-nitroaniline from aniline?
Step 1: Acetylation of Aniline. In the first step we need to put the removable acetyl protecting group on the.
