Why the bond angle (H--N--H) in NH4 +is greater than NH3?????

NH3 has a lone pair of electrons, which repels the H atoms strongly. hence bond angle 107 and is trigonal pyramidal.

While NH4+ doesnt have any lone pair hence there is no replusion as in NH3 hence, its HNH bond angle is greater 109.5 and is tetrahedral.

it is because repulsion in N--H bond in NH+4 is less as compared to NH3
