A) \[B{{r}^{-}}>C{{l}^{-}}>C{{H}_{3}}CO_{2}^{-}>H{{O}^{-}}>{{H}^{-}}\]
B) \[{{H}^{-}}>O{{H}^{-}}>C{{H}_{3}}C{{O}_{2}}>C{{l}^{-}}>B{{r}^{-}}\]
C) \[B{{r}^{-}}>C{{H}_{3}}C{{O}_{2}}>CF>O{{H}^{-}}>{{H}^{-}}\]
D) \[C{{H}_{3}}C{{O}_{2}}>B{{r}^{-}}>C{{l}^{-}}>O{{H}^{-}}>{{H}^{-}}\]
Correct Answer: A
Solution :
The correct order of leaving group ability in a nucleophilic substitution reaction is \[B{{r}^{-}}>C{{l}^{-}}>C{{H}_{3}}CO{{O}^{-}}>H{{O}^{-}}>{{H}^{-}}\] Because the best leaving group is that which is conjugal base of strong acid.You need to login to perform this action.
