Arrange the anions $(p) \bar{C} H_{3}, (q) \bar{N} H_{2}, (r) O H^{-}, (s) F^{-}$ in decreasing order of their basic strength

Options:

Answer:

Solution:

$S t r e n g t h$ $o f$ $c o n j u g a t e$ $b a s e \propto \frac{1}{A c i d i c s t r e n g t h}$
As acidic strength is $C H_{4} < N H_{3} < H_{2} O < H F$
So conjugate base strength is $C H_{3}^{-} > N H_{2}^{-} > O H^{-} > F^{-}$
