Why is benzene extraordinarily stable through it contains there double bonds?

Explanation

Resonance and delocalisation of electrons generally leads to the stability of benzene molecule.

The dotted circle in hybrid structure represent the six electrons which are delocalised between the six carbon atoms of Benzene ring, Therefore, presence of delocalised `pi-e^(-)s` in benzene ring makes it more stable than the hypothetical cyclohexatriene.
