Question

Which of following shape can not be derived from $s{p}^3{d}^2$ hybridisation of the molecule having single central atom.

• A. Octahedral
• B. Trigonal pyramidal
• C. Square planar
• D. Linear

Answer 1

Answer: (B), (D)

The correct options are
B Trigonal pyramidal
D Linear

Hybridisation is $s{p}^3{d}^2$
i.e. $\text{bond pair + lone pair}\Rightarrow 6+0\Rightarrow \text{octahedral}\left(S{F}_6\right)$
$\text{bond pair + lone pair}\Rightarrow 5+1\Rightarrow \text{square pyramidal}\left(Br{F}_5\right)$
$\text{bond pair + lone pair}\Rightarrow 4+2\Rightarrow \text{square planar}\left(Xe{F}_4\right)$
$\text{bond pair + lone pair}\Rightarrow 3+3\Rightarrow \text{No possible situation}$
$\text{bond pair + lone pair}\Rightarrow 2+4\Rightarrow \text{No possible situation}$
