A) \[B{{F}_{3}}\]
B) \[N{{H}_{3}}\]
C) \[C{{N}^{-}}\]
D) \[O{{H}^{-}}\]
Correct Answer: A
Solution :
Key Idea : Electron donors having lone pair of electrons are nucleophile. (i) \[B{{F}_{3}}\] is not nucleophile because it does not have lone pair of electrons. It is intact Lewis acid because it accepts pair of electron (ii) \[N{{H}_{3}},\,\,C{{N}^{-}}\] and \[O{{H}^{-}}\] all have lone pair of electrons, so they are nucleophiles.You need to login to perform this action.
