Question

Two of the following have Same shape ni3,i3-,so3-2,no3-

Answer 1

given
NI3, I3-, SO3 -2, NO3 -1
for
NI3 have 3 bond pairs and 1 lone pair so NI3 shape pyramidal
for
I3- have 2 bond pairs and 3 lone pairs so I3- shape linear

for
SO3 -2 have 3bond pairs and 1 lone pairs so SO3 -2 shape pyramidal

for
NO3- have 3 bond pairs and 0 lone pair so, NO3- shape triangular

hence SO3 -2 and NI3 have same shape
