Why is nitrobenzene more stable than benzene?

In nitro benzene, the nitro group is attached to the benzene ring which is a ring deactivating group. In benzene, no group is attached so it is neither ring activation nor ring deactivating. Thus, the reactivity of phenol will be higher than benzene and the nitrobenzene will be least reactive.

Why nitrobenzene is used as solvent in Friedel Craft reaction?

Nitrobenzene contains an electron-withdrawing nitro group directly bound to the phenyl ring. As −+N(=O)O− , i.e. a quaternized nitrogen, it serves to deactivate the aromatic ring towards electrophilic aromatic substitution. And of course, a lack of reactivity is required of a solvent in an organic reaction.

Can nitrobenzene undergo Friedel Crafts acylation?

Since the nitro group is known to be a very powerful deactivating group, nitrobenzene cannot undergo a Friedel-Crafts acylation under normal conditions.

Which of the following is used as solvent in the Friedel Crafts reaction?

Nitrobenzene
Nitrobenzene is used as a solvent in the Friedel Crafts reaction.

What is the use of nitrobenzene?

Most of the nitrobenzene produced in the United States is used to manufacture a chemical called aniline. Nitrobenzene is also used to produce lubricating oils such as those used in motors and machinery. A small amount of nitrobenzene is used in the manufacture of dyes, drugs, pesticides, and synthetic rubber.

What is nitrobenzene used for agriculture?

The main advantages of nitrobenzene # It helps the plant to increase CN ratio significantly # It increases plant size and helps for flowering # It enhances the plant canopy and induces flowering and increases the yield # It can be used in all major agriculture crops through foliar application # It is compatible with …

Why does nitrobenzene have a lack of reactivity?

Explanation: Nitrobenzene contains an electron-withdrawing nitro group directly bound to the phenyl ring. As #-^+N(=O)O^-#, i.e. a quaternized nitrogen, it serves to deactivate the aromatic ring towards electrophilic aromatic substitution. And of course, a lack of reactivity is required of a solvent in an organic reaction.

How does nitrobenzene give different products in different medium?

Nitrobenzene gives different products in different medium by using different reducing agent. Nitrobenzene on reduction with Zn/HCl or Sn/ HCl gives aniline. Nitrobenzene when reduced by hydrogen in presence of nickel or platinum as a catalyst gives aniline.

Is nitrobenzene soluble or insoluble in water?

It is insoluble in water but soluble in organic solvent. It’s boiling point is 210 0 C. Nitrobenzene gives different products in different medium by using different reducing agent. Nitrobenzene on reduction with Zn/HCl or Sn/ HCl gives aniline.

How do you make nitrobenzene from chlorobenzene?

Nitrobenzene can also be prepared from alkyl halides (such as chlorobenzene), in which case the halogen (such as chlorine) can easily be substituted for the nitronium ion. Lesson Summary. Nitrobenzene is a toxic derivative of benzene. Its pie bonding further stabilizes the benzene ring, making it very unreactive.
