Out of the two bromoderivatives,C_(6)H_(5)CH(CH_(3))Br and C_(6)H_(5)CH(C_(6)H_(5))Br, which one is more reactive in S_(N^(1)) reaction and why? |
Answer» Solution : In the `S_(N^(1))` reaction, the REACTIVITY of an alkyl halide depends upon the stability of the CARBOCATION which is forme din Although both the carbocations are secondary in nature, the carbocation formed in the second reaction is more resonance STABILISED DUE to the presence of two phenyl groups that are involved in conjugation. therefore, the corresponding halogen DERIVATIVE is more reactive. |
