Benzene does not undergo these reaction due to the aromaticity of the ring. The conjugated, cyclic double bond system provides about 38 kcal/mol of stabilization to the molecule. For addition to occur, it would have to disrupt the aromatic nature of the ring and this is very difficult.

Benzene is what kind of bond type?
Benzene has covalent bonds. Each of the six carbons in benzene is sp2 hybridized meaning the ring has both sigma bonds and pi bonds. Benzene is aromatic meaning its pi electrons are delocalized and form a pi system.
How many pi bonds are in benzene?
6
Why is benzene less reactive than alkenes though it has three pi bonds?
It's because of resonance, which is the delocalization of electrons (the pi electrons). This delocalization lowers the potential energy of the benzene and thus renders in more stable.
Does benzene conduct electricity?
No, Benzene does not conduct electricity. Contrary to graphite which has a delocalized pi electron which enables current to pass, benzene's dolocalized pi electron cloud is in the benzene ring, and is unable to partake in any electrical conductivity activity.
Why benzene cannot decolourize KMnO4 while alkenes can decolorize?
KMnO4 will add across the double bond of alkenes (or alkynes) resulting in the docolouring of KMnO4 but not an alkane such as ethane.
Benzene ring has three pi-bonds in it but is still quite stable.explain?
Benzene has a property called resonance. Because of this, the three pi-bonds in benzene act as a rather delocalized single pi-structure. So, benzene does not actually have 3 distinct pi-bonds. This pi-structure is stable, which explains why benzene is more stable than it would be if it had 3 pi-bonds.
Is benzene a pi acid?
No, benzene is always a neutral compound.

Why benzene only yield one monosubstituent?
Because all the six positions of benzene are equivalent due to pi electronic cloud (instead of isolated pi bonds).

What is structural formula of Benzene?
i think its C6H6i just googled benzene and that was the first linkthe strucure of benzene with carbon showing sp2 hybirdization of orbitals with pi electron cloud on aboove and below the plane , it is C6H6

Why benzene undergoes electrophilic substitution reaction whereas alkenes undergoes addition reaction?
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.
