Bacause of the resonance stabilization...

Bacause of the resonance stabilization of Arylhalides they are unreactive toward normal nuclephilic substitution reactions . However arylhalides having strong electron withdrawing groups at ortho and para positions give aromatic nucleophilic substitution reactions `(S_(N)Ar` mechanism ) , which involves a resonance stablilized carbanion called Meisenheimer complex

Which of the following statement is `//` are true ?

A

`S_(N)Ar` proceeds through elimination `//` addition mechanism

B

Formation of elimination product is the rate determing step

C

Formation of Meisenheimer complex is the rate determining step

D

`S_(N)Ar` mechanism involves inversion of configuration
