Class XI Hydrocarbons Page 397

Answer 1

Benzene is extra ordinarily stable though it contains three double bonds it's pie electrons oscillate all the time.

Answer 2

Resonance and delocalization of electrons leads to stability of any molecule .
since, in 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 atoms of the ring , therefore it is extraordinarily stable.
