Question

Which of the following deviates from the rest in geometry?

• A. $C{H}_4$
• B. ${Cl{O}_4}^{-1}$
• C. ${S{O}_4}^{-2}$
• D. $B{F}_3$

Answer 1

The correct option is D

$B{F}_3$

$B{F}_3$ is ${sp}^2$ hybridised.
$C{H}_4$, ${Cl{O}_4}^{-1}$ and ${S{O}_4}^{-2}$​​​​​​​​​​​​​​ are ${sp}^3$ hybridised.
