Question

Write down the hybridisation and geometry of $F_{2}SeO$ and $I{O}_2{F}_2$

Answer 1

$F_{2}SeO$ ${\left[{IO}_2{F}_2\right]}^{-}$

Central atom is $Se$ [selerium] Central atom is $I$ [Iodine]

Hybridisation $=\frac{1}{2}[V+M-C+A]$ Hybridisation $=\frac{1}{2}[V+M-C+A]$

$=\frac{1}{2}[6+2-0+0]$ $=\frac{1}{2}[7+2-0+1]$

$=\frac{8}{2}=4$ $=\frac{10}{2}$

$={SP}^3$ $={SP}^{3}d$

Geometry $=$ Tetrahydral Geometry $=$ trigonal pypramidal

Shape $=$ trigonal pyramidal Shape $=$ Sea-saw
