WebSo, the nucleophilicity should depend on which among them is more basic. Now, since N is less electronegative than O, it's lone pair is more readily available than that of O H X −. So, according to me, N H X 2 X − should be more nucleophilic than O H X −, but the answer given is the opposite, that is, O H X − is more nucleophilic than N H X 2 X −. how old is sssniperwolf husbandWebThe best method for reduction of NO2 to NH2 is to use H2 /Pt in acetic acid.
