S b F 5 reacts with X e F 4 to form an adduct. The shapes of cation and anion in the adduct are respectively
Options
- ASquare planar, trigonal bipyramidal
- BT-shaped, octahedral
- CSquare pyramidal, octahedral
- DSquare planar, octahedral
Correct answer
B. T-shaped, octahedral
Step-by-step solution
XeF 4 + SbF 5 → [XeF 3 ] + [SbF 6 ] − → [XeF 3 ] + sp 3 d T-Shaped + [SbF 6 ] − sp 3 d 2 octahedral As [ X e F 3 ] + has 3 bond pair and 2 lone pair of electron so it has s p 3 d hybridisation and T-shape. [ S b F 6 ] - has 6 bond pair electrons so it is s p 3 d 2 hybridise and octahedral in shape.
