Question

The number of molecules having octahedral geometry.
(a) $PB{r}_5(s)$
(b) $S{F}_6$
(c) $PC{l}_6^{\Theta }$
(d) ${\left[Si{F}_6\right]}^{2-}$
(e) $\left[PC{l}_4^{+}\right]$
(f) $Xe{F}_6$

Answer 1

Answer: 4

(a) $PB{r}_5(s)$ exists as ${\left[PB{r}_4\right]}^{+}B{r}^{-}:$ Hybridisation of $P:s{p}^3:$
Tetrahedral
(b) $S{F}_6:$ Hybridisation of $s:s{p}^3{d}^2$

(c) $PC{l}_6^{-}:$Hybridisation of $P:s{p}^3{d}^2$

(d) ${\left[Si{F}_6\right]}^{2-}:$ Hybridisation of $Si:s{p}^3{d}^2$, octahedral
(e) $PC{l}_4^{+}:$Hybridisation: $s{p}^3$

(f) $Xe{F}_6:$ Hybridisation: $s{p}^3{d}^3$
