Write the conditions which proves exceptional stability of bezene. |
|
Answer» Solution :The following conditions proves the excepetional stability of BENZENE. (i) Benzene resist the addition reaction with respect to ALKENE. (ii) Although having LESS amount of `PI` -bond and Hydrogen atom, benzene easily gives substitution reaction. (iii) Benzene possess neither 154 pm length for C-C single bond length nor 133 pm length for C=C but it possess 139 pm intermediate bond length. (iv) Benzene has least hydrogenation ENTHALPY, only `36 K Cal mol^(-1)` respect to cyclohexatriene. Resonance energy of benzene is `36 K cal mol^(-1)`. (v) Benzene is stable due to its aromatic character. |
