Can benzene be nitrated?
Nitration of Benzene Benzene reacts with concentrated nitric acid at 323-333k in the presence of concentrated sulphuric acid to form nitrobenzene. This reaction is known as nitration of benzene.
What are the derivatives of benzene?
1 Benzene Derivatives. The benzene derivative compounds detected by GC-MS are toluene, dimethylbenzene, and trimethylbenzene. For poly(BA-a) and poly(Ph-a), m-xylene and 1,3,5-trimethylbenzene compounds have the highest intensities.
Which is easily nitrated phenol or benzene?
Out of benzene and phenol, phenol is more easily nitrated because of the presence of -OH group in phenol increases the electron density at ortho and para – position.
What happens when nitro benzene is nitrated?
The nitration of benzene Nitration happens when one (or more) of the hydrogen atoms on the benzene ring is replaced by a nitro group, NO2. Benzene is treated with a mixture of concentrated nitric acid and concentrated sulfuric acid at a temperature not exceeding 50°C.
How aniline is nitrated?
Direct nitration of aniline with nitric acid gives a complex mixture of mono, di- and tri- nitro compounds and oxidation products. If −NH2 group is protected by acetylation and then nitrating mixture, p-isomer is the main product.
How is toluene nitrated?
Toluene undergoes nitration to give ortho and para nitrotoluene isomers, but if heated it can give dinitrotoluene and ultimately the explosive trinitrotoluene (TNT). Figure 2: Reaction of nitric acid and sulfuric acid with toluene.
How are benzene derivatives formed?
Benzenes can be combined with other compounds during chemical reactions where new groups replace the hydrogen atoms on some of the carbon atoms in the ring to form benzene derivatives. The resulting molecules are quite versatile and are used in a variety of applications today.
Which is not the derivative of benzene?
Explanation: All the mentioned compounds in the options are not derivatives of Benzene. In fact, Pyrrole itself has many derivative compounds such as hydroxypyrroles, as well as aldehydes, ketones, acids, esters, and various reduced forms, such as pyrrolines and pyrrolidines.
Why phenol is nitrated easily but benzene Cannot?
Out of benzene and phenol, phenol is more easily nitrated because the presence of –OH group in phenol increases the electron density at ortho and para-position So, the correct answer is “Option A”.
Why is phenol more nitrated than benzene?
One of these lone pairs are partially donated/delocalised into Benzene’s pi-system, which increases the electron density across the molecule. This makes Phenol more susceptible to attack from electrophiles than Benzene and hence is more easily nitrated!
How many nitrated products would you get from the nitration of methylbenzene?
The nitration of methylbenzene (toluene) You get a mixture of mainly two isomers formed: 2-nitromethylbenzene and 4-nitromethylbenzene.
Can aniline be nitrated directly?
Direct nitration of aniline is not carried out because by doing this it gets oxidised into protonated aniline which give 47% m-nitroaniline .
