Question

The basic species are arranged in decreasing order of basicity in the sequence: A)F^- > OCH₃^- > NH₂^- > CH₃CH₂^- B)OCH₃^- > CH₃CH₂^- > NH₂^- > F^- C)CH₃CH₂^- > NH₂^- > OCH₃^- > F^- D)NH₂^- > CH₃CH₂^- > F^- > OCH₃^- E)NH₂^->OCH₃^- > CH₃CH₂^- > F^-

Quizplus · Accepted Answer

The basic species are arranged in decreasing order of basicity in the sequence CH₃CH₂^- > NH₂^- > OCH₃^- > F^-. This is because CH₃CH₂^- is a strong basic compound due to the presence of two amino groups whereas F^- has no functional group to show basicity. Therefore, C is the best choice.
