Answer

Benzene contain 3 double bonds yet it behaves like a saturated compound

this is because of the aromaticity of Benzene .In all the benzene all the six π- electrons of the three double bonds are completely delocalized to form one lowest energy molecular orbital which surrounds all the carbon atom.

The resonance structure makes the benzene unreactive.
