Abhishek Priyam ·

Kaun sa double bond...I me jo ek hai wo... heating se break kyun hoga... benzene ka to V2O5 se hua tha...

and theres no 1 kg V2O5 ki sab co2 ban jaye..:P

Abhishek Priyam ·

this is trajedy of chemistry... u have to take somethings for granted...

If V2O5 is added to benzene that is formed...(along with some other oxidation products.. but major are they(I J)) because its experimental.. and we only try to give possible explanation...
