How do you get p-nitroaniline from p-nitroacetanilide?
Place 30 g of p-nitroacetanilide and 150 ml of 70% H2SO4 (prepared by adding 100 ml conc. acid to 75 ml water carefully) in a round-bottomed flask. Reflux the mixture for 20-30 min. and pour the hot solution into 1000 ml of cold water.
Is 4 Nitroacetanilide soluble in water?
|Solubility Information||Solubility in water: 2.2g/L (25°C)|
What is the formula of P Nitroacetanilide?
Why is P Nitroacetanilide the major product?
Give reason. This reaction is electrophilic substitution reaction and the nitronium ion formed is directed towards ortho and para positions. Due to steric hindrance in ortho position the nitronium electrophile is directed more towards para position. Therefore, para product is major.
Why is P Nitroacetanilide yellow?
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. That can be seen easily because the product obtained is very pale yellow, bright yellow indicates presences of aniline.
How do you separate P-Nitroacetanilide and O Nitroacetanilide?
To separate p-nitroacetanilide from this mixture, the reaction mixture is recrystallised in ethanol, so that the more readily soluble o-nitroacetanilide dissolves in ethanol and pure p-nitroacetanilide separates out.
Why is P-Nitroacetanilide the major product?
How P Nitroacetanilide is separated from O Nitroacetanilide in the crude sample?
How p-nitroacetanilide is separated from o-nitroacetanilide in the crude sample? o-nitroacetanilide is more soluble in ethanol so that it remains in the mother liquor and during crystallization only p-nitroacetanilide separates out.
How do you separate p-nitroacetanilide and O Nitroacetanilide?
What is the use of p-nitroacetanilide?
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.

How are P-nitroacetanilide isomers hydrolyzed in sulfuric acid flask?
A suspension of p -nitroacetanilide isomers resulted. To hydrolyze the p -nitroacetanilides to their corresponding p -nitroanilines, the mixture was heated. The dilute sulfuric acid already present in the flask served as the hydrolyzing medium. Heating the mixture allowed the solids to dissolve.
