MHT CET 2026 Chemistry question

Which of the following has the highest nucleophilicity ?

(A)
(B)
(C)Correct
(D)

Answer: (C)

Solution

All four species are isoelectronic anions with the donor atom in period 2 (F, O, N, C). Along a period, nucleophilicity (like basicity) decreases as electronegativity increases, because a less electronegative atom holds its lone pair less
