How is IBr- linear??? It has 2 bond pairs and 3 lone pairs and hence sp3d hybridisation but how linear structure??? explain...

IBr₂^-

two bond pairs & 3 lone pairs ...

according to bent rule , for SP³d hybridisation

all lone paires should be in equitorial position so as to minimize LP-LP repulsion...

if all three lone paires in IBr₂^- are placed at equitorial position then both Br will be

along axial position so it will be linear structure ...(all atoms lie in a same line)

approve my answers if u like ...... for more doubts ask on this forum i wl try to give u the solutions in short tym...
