Statement 1 :p-fluoroanilinium ion is more acidic than anilinium ion.Statement 2 : Electron density in the N-H bond of p-fluoroanilinium ion decreases and release of a proton from p-fluoroanilinium ion is much easier than from anilinium ion.

Due to -I-effect of F-atom, it withdraws electrons from N⊕H3 group. As a result, electron density in the N-H bond of p-fluoroanilinium ion decreases and hence release of a proton from p - fluoroanilinium ion is much more easier than from anilinium ion. Thus, p-fluoroanilinium ion is more acidic than anilinium ion.
