Answer & Solution

Correct Answer

(A) \({I^ - } < {F^ - } < H{S^ - } < N{H_2}^ - \)

Step-by-step Solution

Detailed explanation

The species with the greatest proton affinity will be the strongest base, and its conjugate acid will be the weakest acid. The weakest acid will have the smallest value of \(K_a\). Since \(HI\) is a stronger acid than \(HF\) which is a stronger acid than \(H_2S\), a partial…
