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.
In reality, benzene does not contain alternating single and double bonds. It is more accurate to say that each carbon-carbon bond is in an intermediate state between a single and a double bond. Benzene therefore displays a property known as resonance.
As the molecular formula for benzene is C6H6 so acetylene CH Triple Bond CH should be its monomer.
Benzene is stable towards oxidation of KMnO4 because it is a stable aromatic molecule. For an oxidation there would have to be a reaction, but since there is no reaction it is stable. Benzene is stable until there is a catalyst such as FeCl3, FeBr3, AlCl3, etc. This type of catalyst is used because it makes the bonding molecule more electrophilic and so it wants to attach to the electron-rich, also know as nucleophilic, benzene ring.
These bonds are covalent.
Helium doesn't form any kind of chemical bond. Every atom has its specialty, they don't form every type of bond.

If you could add a pair of hydrogen ions to any double bond of the benzene ring it would not be benzene anymore, on the one hand.
c-c bond length in benzene is 1.397 angston and that of ethene is 1.34 angston structure of benzene is a resonance hybrid, therefore all the c-c bond lengths are equal but different from those in alkanes,alkenes, and alkynes.
Benzene is an organic substance, a hydrocarbon.
As the molecular formula for benzene is C6H6 so acetylene CH Triple Bond CH should be its monomer.
The two resonance configuration is equally probable in benzene. i.e. all the c-c bonds have 50% probability of single bond and double bond. As a result all the bonds become equal.

Ionic bond between H+ ions and I- ions in HI molecule.
Benzene has the structure C6H6 so should have double bonds but it does not instead it has a unsaturated electron above or below it. This is also known as an area of high electron density.
Adding halogens to alkene groups (X2) requires that the product adopt an anti configuration. Hexene will also lose its double bond upon bromination. Benzene is energetically unfavorable when a reaction attempts to break its double bond. The resonance benzene has makes it very stable, and thus very hard to break.
