Question

Which of the following is strongest base?
(A) $\mathrm{Br}^{-}$
(B) $\mathrm{OH}^{-}$
(C) $\mathrm{CN}^{-}$
(D) $\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{O}^{-}$

Accepted Answer

***B*** ∻Key Concept∻ ⚹Basicity in Aqueous Solution⚹ ∻Explanation∻ ⚹Among the given options, $\mathrm{OH}^{-}$ is the strongest base in aqueous solution because it readily accepts a proton to form water, which is a very stable molecule. The other anions are less basic due to their lower tendency to accept protons compared to $\mathrm{OH}^{-}$.⚹◊What is the relationship between the strength of a base and its conjugate acid?⍭ Generate me a similar question◊
