  tert-Butyl bromide reacts with aq. NaOH by mechanism while w-butyl bromide reacts by mechanism. Why ?        

Answer:

  On the other hand, n-butyl bromide does not undergo ionization to profluce w-butyl carbocation because it is not stable. Therefore, it prefers to undergo reaction by  mechanism which occurs in one step through a transition state involving nucleophilic attack of the ion from the back side with simultaneous  expulsion of  ion from the front side.
