How can you prepare para-nitro acetanilide from acetanilide?
Para-nitro acetanilide can be prepared from acetanilide by first reacting it with concentrated nitric acid and sulfuric acid to introduce the nitro group. The reaction should be carefully monitored to avoid excessive heat generation and the formation of unwanted by-products. After the reaction is complete, the product can be isolated and purified using appropriate techniques.
Why add nitric acid and sulphuric acid to acetanilide?
Nitric acid and sulfuric acid are added to acetanilide to facilitate the nitration reaction. Nitric acid provides the nitronium ion needed for nitration, while sulfuric acid acts as a catalyst and helps in protonating the acetanilide molecule. This process allows for the substitution of a nitro group onto the acetanilide molecule.
Why is synthesis of p-nitro acetanilide carried out at low temperature?
Synthesis of p-nitro acetanilide is carried out at low temperature to minimize side reactions and to control the rate of the nitration reaction. Low temperature helps to improve the selectivity of the reaction, favoring the desired product formation over potential byproducts.
Among benzyl amine aniline acetanilide and p-nitro aniline which is the most basic compound?
Among the compounds listed, aniline is the most basic as it has a lone pair on the nitrogen atom that can readily accept a proton. Benzylamine and p-nitroaniline are less basic due to the presence of electron-withdrawing groups, while acetanilide has a resonance-stabilized amide group that reduces its basicity.
Introduction of p-nitro acetanilide?
The reaction type is EAS (Electrophilic Aromatic Substitution). When dealing with aromatic substitutions you have to take into consideration what positions the different types of substitutes prefer. In this situation you are dealing with Nitro-groups (NO2), which are said to prefer meta. The mechanic itself is quite simple, you have to start out by figuring out the product of the reaction between the acids, which generate the nitro-group. What happens when you add H2SO4 and HNO3 together? (These are the most commonly used reagents in this reaction). You know that one nitro group is generated, the rest is simple. Just remember the ion from sulfur acid, this will play a key role later on. So NO2 groups are meta-positioning, thus the double bond from the aromat will attack NO2+. After that you draw the resonance, and finish with a hydrogen being attacked by the ion from sulfuric acid, returning the double bond and giving you your product.

Why para-nitro acetanilide is insoluble in water whereas ortho-nitro acetanilide is soluble in water?
p-nitro phenol has a symmetric structure as compare to o-nitro phenol so it has higher dipole moment or polarity so is more soluble.
When was Nitro Function created?
Nitro Function was created in 1971.
Is the compound of nitrogen and sulfur acetic?
No. 'Acetic' refers to acetic acid; a compound involving nitrogen is usually called nitro- and sulfur is called thio-.

Why aniline is more reactive than acetanilide toward electrophilic substitution?
For acetanilide, resonance delocalization of the nitrogen lone pair electrons to the aromatic ring is less favored because the positive charge on nitrogen is next to the positively polarized carbonyl group. Resonance delocalization to the carbonyl oxygen is favored because of the electronegativity of oxygen. Since the nitrogen lone pair electrons are less available to the ring than in aniline, the reactivity of the ring toward electrophilic substitution decreases.

How can seprate p-nitro acetanilide mixture of para and ortho acetanilide?
The amide group on acetanilide is an ortho/para director, so a simple nitration should work: a mixture of sulfiric acid and nitric acid should be sufficient. Afterward, separation of the ortho and para compounds (by column chromatography, probably) would be necessary.
