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 −. images of lake washington

"WebYou can think of the primary amine as a slightly modified ammonia molecule. It has a lone pair on the nitrogen atom and an even bigger - charge than in ammonia. That means that the primary amine is going to be a better nucleophile than ammonia is. You can therefore get a reaction between it and a molecule of the halogenoalkane. " - From oh to nh2
