Question

Among the following compounds, which compound is polar as well as exhibit $s{p}^2$- hybridisation by the central atom?

• A. $H_{2}C{O}_3$
• B. $Si{F}_4$
• C. $B{F}_3$
• D. $HCl{O}_3$

Answer 1

The correct option is A $H_{2}C{O}_3$

(i) $Si{F}_4$ and $HCl{O}_3$ has $s{p}^3-hybridisation$.
(ii) $B{F}_3$ and $H_{2}C{O}_3$ has $s{p}^2-hybridisation$ but $B{F}_3$ is non-polar.
$\therefore$ Correct answer is $H_{2}C{O}_3$.
