preparation of m-nitro benzoic acid from benzene
The substitution reactions of phenol are easier than benzene, phenol directly reacts with bromine and gives tribromo phenol while benzene requires FeCl3 as a catalyst and gives mono bromo phenol.
Benzene does not react directly with potassium permanganate (KMnO4) under normal conditions. Benzene is a stable aromatic compound and does not undergo typical alkene or alkane reactions with oxidizing agents like KMnO4.
This is because chlorine is an electronegative group and is pulling electrons away from benzene. This makes the ring less reactive and more positive. Then when a positive electrophile tries to attach, the benzene does not want to react.
The benzene molecule is unsaturated but the double bonds present inside the benzene ring are delocalized due to bond resonance (pi structure). This makes the double bonds of benzene much less reactive then more discreet double bonds (as in ethylene). This structure makes it behave more like a saturated compound, preferring substitution reactions over addition reactions. It is resistant to addition reactions across the double bond because such a reaction reduces the resonance stabilization energy. However, when reactions do occur, resonance stability is almost always re-established (Birch Reduction reactions are exceptions. See related link).
Fractional distillation is commonly used to separate benzene from a mixture of benzene and methyl benzene. Benzene has a lower boiling point compared to methyl benzene, allowing it to be separated by distillation based on the difference in their boiling points.

The benzene functional group is significant in organic chemistry reactions because it provides stability and aromaticity to molecules. This stability allows benzene-containing compounds to participate in various reactions, making them versatile building blocks in organic synthesis.
The Benzene hexa clorief is prepared by light-induced addition of chlorine to benzene.
A mitochondrion is a bean-shaped organelle in cells that has inner membranes where chemical reactions involved in energy production (ATP synthesis) take place.
Benzene is generally more reactive than ethane due to its unique structure and the presence of a conjugated π-electron system. While ethane is a saturated hydrocarbon that primarily undergoes reactions such as combustion and substitution, benzene can participate in electrophilic aromatic substitution reactions due to its delocalized electrons. This makes benzene more susceptible to reactions with electrophiles. However, benzene's stability also means it is less reactive in some conditions compared to alkenes or alkynes.
The ortho position in benzene is significant in chemical reactivity because it is one of the positions where substitution reactions can occur. Substitution reactions at the ortho position can lead to the formation of different compounds with unique properties. This makes the ortho position important in understanding the reactivity of benzene and its derivatives.
The benzene dipole moment is significant in understanding its chemical properties because it helps explain the molecule's unique structure and reactivity. Benzene's symmetrical hexagonal shape and lack of a net dipole moment contribute to its stability and resistance to reactions. This property is crucial in explaining benzene's behavior in various chemical reactions and its role in organic chemistry.
Cyclohexane can be prepared from benzene through catalytic hydrogenation. In the presence of a catalyst such as platinum or palladium, benzene can be reacted with hydrogen gas under high pressure and at high temperature to produce cyclohexane.
The cation formed upon addition of an electrophile to benzene is highly stabilized by resonance,whereas the cation formed to an alkene is stabilized by hyperconjugation. The loss of a proton in benzene is favourable due to the restoration of the cyclic pi-system.
Benzene is less reactive than alkenes because it has a stable aromatic ring structure, which leads to a high degree of resonance stabilization. This stability reduces the tendency of benzene to undergo addition reactions that are commonly seen with alkenes. Additionally, the delocalization of electrons in the benzene ring provides extra stability, making it less likely to undergo reactions that would disrupt this resonance.
A benzenonium ion is a positively charged ion that results from the addition of a proton (H+) to a benzene ring. It is a reactive species that is not stable under normal conditions and is usually involved in electrophilic aromatic substitution reactions.
Phenol and benzene are both aromatic compounds, but phenol has a hydroxyl group (-OH) attached to the benzene ring, making it more reactive than benzene. Phenol can undergo reactions such as oxidation and substitution more readily than benzene. Additionally, phenol is more acidic than benzene due to the presence of the hydroxyl group.
