Mark out the incorrect order of nucleophilicity for given nucleophile:

Options

A. `CH_(3)^(ɵ)gtOH^(ɵ)tNH_(2)^(ɵ)gtF^(ɵ)gtI^(ɵ)` (in DMF)
B. `I^(ɵ)gtBr^(ɵ)gtCl^(ɵ)gtF^(ɵ)` ( in `H_(2)O`)
C. `I^(ɵ)gtF^(ɵ)gtOH^(ɵ)gtNH_(2)^(ɵ)gtCH_(3)^(ɵ)` ( in DMSO)
D. `CH_(3)^(ɵ)gtNH_(2)^(ɵ)gtOH^(ɵ)gtF^(ɵ)` (in `H_(2)O)`

Answer

A, C

Explanation

While moving from left to rigt in periodic table nucleophilicity parallels basicity and from top to bottom nucleophilicity is reverse to basicity.
