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 sodium sulphate is added in preparation of para bromo acetanilide?
Sodium sulfate is added in the preparation of para bromoacetanilide to facilitate the separation of the product from the reaction mixture. It helps in forming a complex with excess bromine and bromine water, allowing easy removal of impurities. Sodium sulfate is also used to dry the organic layer during the extraction process.
Why in bromination of acetanilide using bromine in acetic acid give para bromoacetanilide as major product?
Steric hindrance from the bulky acetanilide group directs the electrophilic bromination to the para position, as it is the least hindered position for bromine attack. This leads to the formation of para-bromoacetanilide as the major product.
Why acetanilide brominates in the ortho and para positions and the amount of o-bromoacetanilide?
Acetanilide undergoes bromination in the ortho and para positions due to the presence of the activating amino group that directs the electrophilic bromine to these positions. In the reaction mixture, the para-bromoacetanilide is the major product compared to the ortho isomer, typically in a ratio of about 4:1.
What compound melting point is 118 degrees Celsius?
The compound with a melting point of 118 degrees Celsius is para-dichlorobenzene. It is a solid at room temperature and is commonly used as a moth repellent.

Why does para-chlorophenol melts at 43 degrees Celsius and ortho-chlorophenol melts at 9 degrees Celsius?
34
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.
Why is only 4-bromoacetanilide created mainly from a bromination of acetanilide?
4-bromoacetanilide is mainly formed from the bromination of acetanilide because the bromine atom primarily substitutes the para position on the benzene ring due to steric hindrance, making it the major product. The meta and ortho positions are less favorable due to destabilizing interactions with the amide group.
What is the function of acetic acid in the preparation of para nitro acetanilide?
Acetic acid acts as a solvent in the preparation of para nitro acetanilide. It helps dissolve the reactants, making it easier for them to mix and react. Acetic acid also helps control the reaction conditions and stabilize intermediates formed during the synthesis process.
What is the melting point of Kevlar?
The melting point of Kevlar is approximately 500 degrees Celsius (932 degrees Fahrenheit). At temperatures beyond this point, the material will start to decompose and lose its structural integrity.
How can seprate p-nitro acetanilide mixture of para and ortho acetanilide?
You can separate the mixture by utilizing chromatography techniques such as column chromatography or thin-layer chromatography. These methods will allow you to separate the para and ortho isomers based on their different physical properties, like polarity or solubility in certain solvents. By running the mixture through a chromatography column or plate, you can isolate the individual components for further analysis or use.
Cual es la estructura de Lewis para el br2?
La estructura de Lewis para el Br2 muestra dos átomos de bromo unidos por un enlace covalente sencillo. Cada átomo de bromo contribuye con un electrón para formar el enlace químico y completar su octeto de electrones. Las dos otras parejas de electrones en cada átomo de bromo se muestran como pares solitarios alrededor de cada átomo.
