Hybridisation of Br is BrO3− Total valence elctrons =7+3×6=25 Charge =−1 Total =25+1=26 =826=3(Q)+2(R)=5 hybridization =dsp3 hybridization of Xe in XeO3 Total valence electrons =8+3×6=26=826=3(Q)+2(R)=5 Hybridization =dsp3 The structure BrO3−and XeO3 is trigonal pyramidal. Caution Molecular structure of NO3−,NH3,NF3= trigonal pyramidal Molecular structure of SO32−= Trigonal Planar Molecular structure of SF4= Seesaw Molecular structure of XeF4= Square Planar
