Where Nu = Nucleophile Find out the correct statement from the options given below for the above two reactions.
Options
- AReaction (I) is of 2 nd order and reaction (II) is of 1 st order
- BReactions (I) and (II) both are of 2 nd order
- CReactions (I) is of 1 st order and reaction (II) is of 2   nd order
- DReaction (I) and (II) both are of 1st order
Correct answer
C. Reactions (I) is of 1 st order and reaction (II) is of 2   nd order
Step-by-step solution
The S N 1 reactions takes place via formation of carbocation. The speed of the reaction depends on the stability of carbocation. Electron releasing groups supports the S N 1 reactions. The S N 2 reactions are takes place through the formation of transition state. The transition can be stabilised by electron withdrawing groups.
