Where Nu = Nucleophile

Find out the correct statement from the options given below for the above two reactions.

  1. Reaction (I) is of 2nd order and reaction (II) is of 1st order
  2. Reactions (I) and (II) both are of 2nd order
  3. Reactions (I) is of 1st order and reaction (II) is of 2 nd  order
  4. Reaction (I) and (II) both are of 1st order

Solution

The SN1 reactions takes place via formation of carbocation. The speed of the reaction depends on the stability of carbocation. Electron releasing groups supports the SN1 reactions. The SN2 reactions are takes place through the formation of transition state. The transition can be stabilised by electron withdrawing groups.
