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.

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.
Do Alkenes have carbon-carbon double bonds?
Alkanes have a single bond, and Alkenes have a double bond. The general form for Alkenes is CnH(2n)
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.
What type of bonds do Alkenes always have?
Single and triple
What type of bonds do alkenes have?
The carbon "skeleton" has one double bond, the rest are single bonds

Which is most reactive ethyne or benzene?
An alkene is more reactive than alkyne. as double bond can donate pair of electron. while in tripple bond the bond length is less than double bond. Alkkynes have more attractive forces than alkene. so alkene is more reactive.

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.
In Chemistry what does Alkenes mean?
Alkenes are hydrocarbons containing carbon-carbon double bonds. There are several different names for alkenes. Some examples are butane, pentene and octadiene.
Do alkanes react with hydrogen?
Alkanes are not really reactive if you compare them to alkenes or alkines. They don't have double or triple bonds, they only have single bonds between their C-atoms so they aren't as reactive as alkenes or alkines. Alkanes are pretty stable since they don't have clouds of delocalised electrons as arenes do. Typical reactions for alkanes are pyrolysis, oxidation and substitution When it comes to substitution, they can substitute one of their C-atoms with a halogen, and the products of that reaction are halogen-hydrogen and halogenalkane For instance, Butane + Cl2 --> Clorobutane + HCl
What is a carbon atoms with double bonds called?
Olefins or alkenes
What are carbons that have carbon-carbon double bonds called?

How many pi bonds are in benzene?
