There is no any triple bond contain in benzene it contain alternate double bond with the chemical formula C6H6 .

HELLO THERE!

It seems that your question has some really critical error!

Benzene does not have ANY Triple bond. However, it has three double bonds in 1,3,5 positions (alternate positions).

To prove it, you can calculate it's Double Bond Equivalent (DBE).

$C-\frac{H}{2}+\frac{N}{2}+1$

We know that in benzene, there are 6 carbons and 6 hydrogens, so C = 6 and H = 6 and N = 0.

So, DBE comes out to be 4.

Note: One double bond makes one DBE and a cycle makes one DBE. (For example, if there are two double bonds in a compound, it’s DBE is 2. The DBE of Cyclopropane is 1, though it doesn’t have any double bond, because the structure is cyclic).

So, DBE of benzene is 4, which proves that there are 3 double bonds and one cycle in benzene (i.e., benzene is cyclic with three double bonds).

HOPE I’M CLEAR!

Thanks!
