The correct increasing order of the reactivity of halides for `S_(N)` 1 reaction is `:`A. `{:(CH_(3)-CH_(2)-X,lt,(CH_(3))_(2)CH-X,lt,CH_(2)=CH-CH_(2)-X,lt,PhCH_(2)-X),(,,,,,,):}`B. `{:((CH_(3))_(2)CH-X,lt,CH_(3)-CH_(2)-X,lt,CH_(2),lt,PhCH_(2)-X),(,,,,,,):}`C. `{:(PhCH_(2)-X,lt,(CH_(3))_(2)CH-X,lt,CH_(2)-CH_(2)-X,lt,CH_(2)=CH-CH_(2)-X),(,,,,,,):}`D. `{:(CH_(2)=CH-CH_(2)-X,lt,Ph-CH_(2)-X,lt,(CH_(3))_(2)CH-X,lt,CH_(3)-CH_(2)-X),(,,,,,,):}` |

Answer» Correct Answer - 1 The relative stability of alkyl carbocation is due to inductive effect hyperconjugation, while that of stable carbocation is due to resonance. The order is `:` `CH_(3)CH_(2)X lt (CH_(3))_(2)CH-X lt CH_(2)=CH-CH_(2)X lt PhCH_(2)-X` |
