Multiple Choice

Which of the following statements about nucleophilic aromatic substitution is not true?

A) Increasing the electronegativity of the halogen increases the reactivity of the aryl halide.
B) Increasing the number of electron-withdrawing groups increases the reactivity of the aryl halide.
C) Electron-withdrawing groups stabilize the intermediate carbanion,and lower the energy of the transition state.
D) When a nitro group is located meta to the halogen,the negative charge of the intermediate carbanion can be delocalized onto the NO₂ group,thus stabilizing it.
