NEET2007ChemistryChemical Bonding and Molecular StructureActual
In which of the following pairs, the two species are iso-structural?
Options
- ASO ₃²⁻ and NO ₃⁻
- BBF ₃ and NF ₃
- CBrO ₃⁻ and XeO ₃
- DSF ₄ and XeF ₄
Correct answer
C. BrO ₃⁻ and XeO ₃
Step-by-step solution
Hybridisation of Br is BrO ₃⁻ Total valence elctrons =7+3 6=25 Charge =-1 Total =25+1=26= 26 8 =3( Q )+2( R )=5 hybridization =d s p^3 hybridization of Xe in XeO ₃ Total valence electrons =8+3 6=26= 26 8 =3(Q)+2(R)=5 Hybridization =d s p^3 The structure BrO ₃⁻ and XeO ₃ is trigonal pyramidal. Caution Molecular structure of NO ₃⁻, NH ₃, NF ₃= trigonal pyramidal Molecular structure of SO ₃²⁻= Trigonal Planar Molecular structure of SF ₄= Seesaw Molecular structure of XeF ₄= Square Planar
