absolutely. :) which part was not clear? the delocalization right?
see, nitrogen, oxygen, these atoms when in the form of a compound, have lone pairs. they can donate these lone pairs to form coordinate bond i’m sure you’re aware of that. In organic chemistry, they act as bases with the help of these lone pairs.
now, when NH2 is attached to benzene forming aniline (i’m unable to paste a diagram of the comppund) , the so the compound is basically C6H5NH2. this N also has lone pairs, but NH2- being a +R group, (resonance) gives away it’s lone pair to benzene ring and the lone pairs get “delocalized” over the entire benzene ring. Now since the lone pairs are delocalized over the ring, Nitrogen doesn’t have them anymore so it’s tendency to act as a base decrease.
